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]....

Asp.net - Dynamically Populating A DropDown Template Control In A Gridview?

May 3, 2012

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?

<ItemTemplate>
<asp:Label runat="server" Text='<%# BuildCategory(DataBinder.Eval(Container, "DataItem.category")) %>'
ID="lblPrice"></asp:Label>
</ItemTemplate>

Make Gridview Checkbox Field Update Boolean Field In Database?

Feb 7, 2011

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...

Asp.net - Which Gridview Event To Use To Add Items To The Dropdownlist Used In The Edit Template

Oct 7, 2010

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?

Dropdownlist Invalid Error Edititem Template Gridview

Sep 15, 2011

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.

Asp.net - GridView AutoGenerateColumns And Sorting?

Aug 31, 2009

gridview sorting in VB.NET: I have a gridview with autogenerate columns = true

<asp:GridView ID="GridView1" FooterStyle-BackColor="Aquamarine"
AutoGenerateColumns="true" AllowSorting="true" OnSorting="Gridview1_Sorting"
AllowPaging="True" PageSize="12" OnRowCreated="GridView1_RowCreated"[code].....

I've declared the sort event handler (OnSorting="Gridview1_Sorting" ), and it works fine.However, then I change the column title (headers as they are in the dataset which I get from the database)

GridView1.HeaderRow.Cells(0).Text = "Document" ' "PROC_UID"
GridView1.HeaderRow.Cells(1).Text = "Process Step" ' "PROC_DOC_UID"

When I set the HeaderRow text, I can no longer click on the title to sort (it also is no longer underlined).How do I correct that?

Manual Sorting For Gridview?

Feb 25, 2011

I have done research on how to manually create sorting in a grid-view and none of it is thorough enough for me to follow. I need more of a step by step solution, like what event should my sorting code go in, how would i enable the headers to allow sorting. normally, i just have .net do this but for some reason this time it doesn't allow it, maybe because i am not using a datasource.that's my code that creates a datable and then binds to the gridview.

Function toptable()
Dim reader As SqlDataReader
cmd.Parameters.AddWithValue("@yeartoget", DropDownList1.SelectedValue)

Create Template Token Variables?

May 4, 2011

Forgive me if this has already been covered in a previous post. I am considering using VB.net for a project but need to know before I dive in if it can perform this particular functionality. The application I wish to develop would need to be able to create html and email templates using variable tokens - what I mean is that users would need to be able to insert into their html or email template previously assigned variables that would send dynamically generated text from the database - so, for example, they could write in their template {title}, or {firstname} {lastname} which would then be replaced by the data from the db.
