Asp.net - Capture The Value Of A Gridview Template Field?
Mar 1, 2012
In the RowDataBound event of an ASP.NET Gridview I am trying to read the value of a Label in a Template Field. I would prefer to capture this value in the RowUpdating Event, but for some reason I seem to recall that it is not possible. Here is the ASP...
<asp:TemplateField HeaderText="Translation" ItemStyle-Width="250" >
<ItemTemplate>
<asp:Label ID="Label11" runat="server" Text='<%# Bind("lang_String") %>' Width="250px"></asp:Label>
</ItemTemplate>
Here is the VB.net code that I am trying to figure out....
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
If (e.Row.RowState And DataControlRowState.Edit) > 0 Then
[code]....

There are lots of questions about this but I've not been able to solve my problem using the answers to any of them (after many, many attempts..)
I'm working in vb.net creating an asp.net web application. I have an SqlDataSource and a GridView on my page.
I want to change the DoNotMail boolean value represented by a Gridview checkbox and automatically update in the database if the checkbox is checked from 0 (False, Will Mail) to 1 (True, Won't Mail) here is the code I used. [code]...
is it possible to do a two way sync on the entire gridview when the user hits a button so you don't have to do an update every time a row is changed? because the user might check the box and then check another box then uncheck a box and it would be a lot of updates...

I have a gridview that I would like to be able to bind to several sqldatasources, but still use template fields. Each datasource is different and would have different columns so I'm not sure how to go about this. Is it possible to define a set of template fields or overlying template per datasource?

I would like my website to allow users to download files which are stored as blobs on the database, the database holds fileID fileName and theFile. I have a grid view with two columns, fileName and a template column, which is databound to fileID and has a linkbutton. When the link is clicked it calls to a function which downloads the file. The function needs the fileID to download the file, how do I get the fileID bound to the selected linkbutton.

I have an admin page where a user will select a document path and add that path to a certain column of a database. I am using a fileupload on the page where they can find the document and copy the path and then paste it into the details view. However, I want to skip this step and I want them to select a document and automatically make the path show up in the details view.
<asp:FileUpload ID="FileUpload1" runat="server" Visible="False" Width="384px" /><br />
<br />
[Code].....
I need to get the fileupload1 into the DOC contenttemplate area so instead of showing an empty textbox it will show just a textbox it will show the fileupload

I have a GRIDVIEW with columns, one of which contains a CSV of possible values for the dropdown that must appear on each row.
Private Sub GridViewParameters_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridViewParameters.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then[code].....
Depending on whether the type of control is a dropdown, textbox, or check box (feined in the table) it hides or shows the relevant control type. If it is a dropdown it needs to get its values from a CSV in a corresponding column. I have a SP that returns a these in table form if passed the id of the relevant row.How do I get that is from the gridview to pass to the drop down and load it correctly?

I would like to show different values in a dropdownlist, while editing a gridview, depending on which user is logged in. For example...
The officer would see "Approved by Officer" status.
The director would see "Approved by Director" status
I am trying to add these programatically to a dropdownlist which I have in the edit template of my gridview (approvalsGrid). Here is my code:
Protected Sub ApprovalsGrid_RowUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles ApprovalsGrid.RowUpdating
Dim ApprovalEditDD As DropDownList = CType(ApprovalsGrid.Rows(ApprovalsGrid.EditIndex).FindControl("ApprovalEdit"), DropDownList)
[code]....
I do not get any errors. But get an empty dropdown with no items. Am I using the correct event?

Error Dropdownlist has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value I have been banging my head over this error for about a week now. I have searched posted on other forums and still no solution to my issue. I have seen the FindControl being suggested but do not know how to implement this.
Basically I have 2 webmethods that reference 2 datasets which then populate my ajax cascading dropdownlist. In insertmode they work great however in editmode i get the above error.I have removed the selectedvalue and added
DataSource='<%# Bind("intRoom") which works sort of except for the fact that when you click edit it does not retain the original value of that particular record. Other things i have tried are as following:adding the items to the itemcollection of the dropdownlist turning appenddataitems to true on also tried to use the findcontrol but dont understand that punching my monitor and slamming my keyboard
Now I know i could get this to work by using a sqldatasource with some t-sql to get my dropdownlist to work however I thought by reusing my webmethods my code would be more professional. So if there is anyone out there that can help me understand why the value for my dropdownlist is not being populated or does not exist during gridview editing Also will post code if asked not sure what you would like to see rather than posting everything.

I have several sqldatasources for my gridview. All of the columns are autogenerated. However they all have some consistent fields and I'd like to make those fields template fields so I can modify the edit template for them such as adding a drop down menu. Is this possible?

I have some of these events in my gridview custom coded. But the real issue here is that I store a previous record, that is, the record that was being changed, or the old.value and I store it in another column. So when the user enters say "< newValue >" without the quotes, the aspx validator rejects the input as dangerous.
I can disable the validation, and html encode the value as it gets written to the db, but when I display the value back in the gridview in the "Previous Value" column it appears like this...< Neutral > semi-colons missing because this site decodes.How I can encode and decode inline in ASPX?How can I encode this template field that is getting entered into a gridview?
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("lang_String") %>'></asp:TextBox>
</EditItemTemplate>
allow certain html characters to be entered into this field only without turning off validation for the entire site.I do need this to apply to the entire column.

I want to populate a checkbox field in a gridview.
I am using the Checked='<%# Convert.ToBoolean(Eval("Inactive")) %>' statement but the issue that I am facing is that in the database some records contain NULL for Inactive. If it encounters a 0 or 1 value it works fine but if NULL it throws an exception.
Kindly guide me how to populate the checkbox so that it should be unchecked even if the field is null.

I have a gridview that displays a calculated field, based on a db source field it populates with.
can i sort by it? i can't seem to figure out how to do it?
example:
my templatefield looks like this:
<asp:TemplateField HeaderText="Category" SortExpression="category" >
<ItemTemplate>
<asp:Label runat="server" Text='<%# BuildCategory(DataBinder.Eval(Container, "DataItem.category")) %>'
ID="lblPrice"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
where category is party of the datasource, but what gets displayed is a calculated value - which is different from the category.what can i put in the "SOrtExpression" to make it sort by the new value - taht gets displayed?

I have a page which has a GridView on it, which is populated from a database. Some of the columns in the GridView have text boxes, as well as Checkboxes.When the user saves the page, the page may error if they have not entered their data correctly. At this point, I need to re-display what they have entered already so they can simply make the correction instead of having to change everything from scratch again.

As you can see I was playing with WithEvents but that didn't seem to help. In the above code all I was trying to get was some kind of reaction to the clicking of a checkbox - but nothing happens (no errors, either).

I'm working on my first T4 code generation tool to add some Stored Procedure helper code to my project. I've created custom types (e.g. StoredProcedure and StoredProcedureParameter to help with my code generation and have included the assembly and namespace references in my code:
<#@ template debug="false" hostspecific="false" language="VB" #>
<#@ output extension=".generated.vb" #>
<#@ assembly name="$(TargetPath)" #>
<#@ import namespace="StoredProcCodeGenerator" #>
This allows me to use my custom types in my T4 template code. However, because my custom types exist in the same project as the T4 template code, I can't recompile my project once I run the template code without restarting Visual Studio. This isn't very much fun.
I read a great article that addresses this exact issue by using the T4 Toolbox, but it's not working. Either I'm implementing the VolatileAssembly directive wrong or the T4 toolbox simply didn't get installed. I'm not sure that the toolbox got installed correctly (I'm using VS 2010 on Win XP).

So I am hacking together an app which listens to traffic using SharpPcap library, it reconstructs the packets from sessions using the code from TpcRcon.
Listening and reconstructing part work on their own . What I want is on each packet arrival main window gets an event so it can display the packet , and when session is reconstructed display a complete packet (I am interested in HTTP ones) . -That is where it breaks with weird symptoms: for example right now it does not stop on invoking stop listening method - the sharppcap library function hangs there forever waiting on this line of code : m_pcapThreadEvent.WaitOne();//wait for the 'stopped' signal from thread
I also had it not working and crashing in sharppcap function because I had omitted one parameter in form delegate- which makes no sense, because form delegate does not deal with packet capture at all and only reacts on "New Packet" event from my "Listener" class (which is only there to notify main form)
My app starts as module main instancing class "Listener". MainForm has it
registered as friend with event and handles even "New Packet"
Main Form:
Private Sub uiListenStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btListenStart.Click
aLogger.AddMessage("Started Listening")
