[Asp.net / Vb.Net] How can I validate my gridview footer checkbox using Javascript. I have a gridview with footer having 8 checkboxes -(chkActive1,chkActive2,.....chkActive3) -
The condition I want to have is - The user need to check atleast 1 checkbox or else the transaction would not allow.
using asp.net/sqldatasource/vb
Is there a way to place the insert row below the header in a gridview instead of in the footer?
I have Gridview with Template Field.And I Put Dropdownlist at footer row of gridview. but when i insert the value from a database table in dropdownlist , than it generate error.
for filling value i declare variable like in databound event of gridview.
for example: dim varclass as new dropdownlist
varclass=Gridview1.footerRow.findcontrol("ddlClass ")
it generate error that: Object reference not set to an instance of an object.
This is my part of code for the grid view
<asp:GridView ID="gridViewCourse"
runat="server"
AutoGenerateColumns="False"
onrowcancelingedit="gridViewCourse_RowCancelingEdit"
onrowdeleting="gridViewCourse_RowDeleting" onrowediting="gridViewCourse_RowEditing"
onrowupdating="gridViewCourse_RowUpdating"

I have a Gridview that I create a dynamic footer wired up to the RowDataBound event.
However there is a 50/50 chance that 3 of the columns will have no data.
I want to be able to dynamically hide the columns with no data if possible.
I have tried doing this in the RowDatabound event by checking if the value is = 0 but that does not work because I think the event is called to early?
Is there anyway to refer to the values in the Footer row after ALL the data has been bound?
Ideally in VB
`Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then

I realise there is a solution for this but I am struggling to get it to convert to VB correctly.I have managed to get a cascading set of dropdowns with data based upon each others results which I was really pleased with.However due to the post back the grid will disappear until the second value is selected and looks awful.Is there anyway within VB to allow the header to stick around if there is no data within the grid view?

View 4 RepliesI use GridView to show/edit data in the database. In the GridView there are two columns called mark1 and mark2. What I want to do is when user clicks update, the program should check if the values entered at mark1 and mark2 sum to 100. If they don't the program should cancel the update and show an error message. How do I do it? I use ASP.NET with VB.
View 1 RepliesI'm playing with XML, DataGridView control, DataSet and DataTable. [code] the user can edit/add records via DataGridView control. So, when the user enters a string value where it is expected to give an integer value(first column and third column), it would give a big error message. Instead of showing that, I would like to apply custom validations.

View 6 RepliesI 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 am putting together a very simple GridView, one of the columns is a CheckBox.I would like the checkbox to update the SQL table as it is checked, the field in my database is a bit field.Currently i have the following:
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" runat="server" Checked='<%# Bind("Purchased") %>' AutoPostBack="true" />
</ItemTemplate>
</asp:TemplateField>
This allows the Checkbox to be checked and unchecked however it does not update my SQL Database. I have tried a couple of things but can't seem to get this to work. I am assuming i'd need to write a custom bit of VB around the 'OnCheckedChanged', i do not want an edit button on the page!
<asp:BoundField DataField="mail" SortExpression="mail" HeaderText="Com Rec">
<HeaderStyle Font-Size="X-Small" ForeColor="White" HorizontalAlign="Left" />
<ItemStyle Font-Size="X-Small" HorizontalAlign="Left" />
</asp:BoundField>
<asp:TemplateField HeaderText="Status Change">
<ItemTemplate>

Firstly i'm not asking for the exact code here but the below is what i'm trying to do:I have a gridview with DropDownList and CheckBox and I have a button outside the gridview that will add a new row within the gridview.I have no problems with the adding row but I have a problem with saving the state of the checkbox/drop down list.Everytime I checked the checkbox and add a new row, all the DDL/CB will be reset.So how can I do it so that when I add a new row, the checkbox that I've checked before will still remain check.

I am using GridView. Because of my search code I am not able to use the automatic delete function that GridView has to offer. I clicked on GridView, said "Add New Column" and added a checkbox column. I want to be able to check one or more boxes and select a button that will delete those rows from the database using a stored procedure. Below is the ASP.net part of my code

The GridView is bound to an Access Table, but I want to update the checkbox using the asp:ButtonField. The best I've been able to do is replace the checkbox with a string value. Below is the code I have now:

If e.CommandName = "check" Then

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 have a GridView with a Checkbox on the first column: Code: The thing is that the Checkbox.Checked always returns False. How can I get the checked state of the Checkboxes in this scenario? Or what would be the best approach into updating the aforementioned column? P.S. Note that click on the checkboxes doesn't post back. Nothing happens on the page until the user clicks Save (and that is the intended behavior).
View 2 RepliesI have aspx gridview with checkbox on evryrow, what is required is whenever we check any of the rows, a query should be launched to change the specific agent -each row consist of agentID, Pass, Status- to Paid Status. using javascriptWhat I need to know is how to loop to get the Checked row and get the ID of the row checked so that I can get THe ID of the Agent in thos row so that I can update its status.using javascriptI found something similar on stackflow:t GridView selected row DataKey in JavascriptBut it is not my case, what is needed is at the check of a checkbox a javascript function should launch through which I could update the selected row in grid view after having the index of this row and this all to avoid refreshing the page.
