I want to create dynamic gridview with checkbox as first column(template).
I have created all thing and its working fine. But the checkbox checked value gets cleared on post back.
[Code]....
This is my template class and adding template field to gridview as below

I've been reading up on the problems with dynamically created controls and how they have been solved. The posts I have come across are creating the controls in a panel or some other open place. I can't seem to get my checkbox to fire the event from inside a gridview. below is the code behind from inside the GridView PreRender event.
[Code]....
..And the Checked Event..
[Code]....
So after all this, nothing happens. I get the postback flash but my command inside the checked event doesn't fire.I tried putting the dynamic creation of the checkbox in Page Load with no effect.. I think because I can't place the checkbox inside the GridView under page load.
I have data in my database and I want one column of the database to be shown as a ckeckbox so the user can select and deselect it.
The colums in my database is called "sendEmail", The values are stored as a "int" with values of 1 and 0. How do I show the value of 1 as checked and the value of 0 as unchecked in a gridview.
I am adding columns dynamically to gridview as [URL] ....
I am adding checkbox and trying to add handler but it is not getting fire
AddHandler lnkView.Click, AddressOf ViewDetails
AddHandler Chk.CheckedChanged, AddressOf ViewDetails

View 5 RepliesI'm having difficulty trying to create and persist controls inside of a gridview during postbacks. I have an unbound Datagrid control which is created with x number of rows and y number of columns during the Page_Load event.
[Code]....
During the RowDataBound event of the GridView, I create a placeholder control and then I create a label and add the label to the placeholder
[Code]....
On the first page load when navigating to the page, the grid dispays perfectly and the labels are created with no issues and I can see the "1" in every single cell of the Gridview. I basically need the labels in the cells to store an ID when the cell is clicked (the click event works with no issues, wired it all up with javascript) and Since the Cells to not exist prior to "Building the matrix" method, How can I persist the Label controls inside of the tablecells between postbacks so I can assign and read values from them.
I've read a number of online posts from 4guys from rolla and they demonstrate how to persist a handful of controls dynamically created in a staticly defined PlaceHolder conrol outside of the complicated setup of the gridview and have failed at adapting them. The golden rule seems to be to 'recreate' the controls during Page_PreInit during the postback, but I can't seem to get it working.
I want to select all checkBox in Gridview when click to header checkBox.I have created design such that CheckBox is not available to header of Gridview.It is in other table. Below is design of gridview.
[Code]....
on page load I fill a repeater with checkboxes. I use a separate tablelist (subcatID & userID) to check if chkbox is checked or not.
On pageload and works fine (according boxes are checked):

When submitting the adapt button .. nothing happens and I can't figure out why ..

I've created a filter textbox for searching my data in gridview..
ex: i've 3 columns in gridview : ID, NAME, DATE

without writing a query repeatedly :(ID like '%" + search + "%') OR (NAME like '%" + search + "%') OR (DATE like '%" + search + "%')
protected void btnCariConnStrSubmit_Click(object sender, EventArgs e) {
string search = ((TextBox)GridView1.HeaderRow.FindControl("txtCariConnStr")).Text;
string sql = "select * from report where (ID like '%" + search + "%') OR (NAME like '%" + search + "%') OR (DATE like '%" + search + "%') ";
reader = mda.GetData(sql, connStr).CreateDataReader();
if (reader.Read()) { dt = mda.GetData(sql, connStr).Tables[0]; BindGridView(dt); lblRecordNotFound.Visible = false; }
else { Bindemptydt(); lblRecordNotFound.Visible = true; }
((TextBox)GridView1.HeaderRow.FindControl("txtCariConnStr")).Text = search;
}

If there's a better way to accomplish what I'm attempting I haven't found it yet. That being said, I have create a gridview like the one here,[URL]And with some minor tweaking it working great for all my fields, checkboxes, etc. The issue is my last column is another gridview, and I'd like it to function the same. that is, a dynamic gridview inside of a dynamic gridview. I get that I have to create it initially with null values or it won't show up. I guess what I'm having trouble figuring out is instead of go will null data in the parent gridviews column, do I place my blank child gridview. Do I create and bind the child gridview first, or second. Generally just not sure. Also, as far as storing the data from the child gridview goes, will each one need it's own datatable?

I have a GridView that I was previously populating via an ObjectDataSource, and this code was working perfectly (ie, when the checkbox was checked Checkbox.Checked = true):
CODE BEHIND:
[Code]....
[Code]....
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="chkRDR1" runat="server"/>
</ItemTemplate>
</asp:TemplateField>

Dim checkbox As CheckBox = CType(row.FindControl("chkRDR1"), CheckBox)
