I am using a datagrid in my website project and be using the select option available i have got the check box options on my datagrid.know how exactly can i retrieve the field say primary key on the table respective to the checked fields.
View 2 RepliesI was trying to find out if there are any check boxes checked in the datagrid, if non of them is checked it should show me an alert to select atleast one.
My problem starts when there is paging in datagrid...
not able to check the entire datagrid at a time in itemDataBound event for the checked check boxes.
I have a data grid and inside that datagrid check box and created using template field.
How can I check that a row in datagrid (not grid view) is checked or not.
For gridview we can use the below in codbehind file,
Boolean isChecked = ((CheckBox)(Row.FindControl("chkDelete"))).Checked;
For datagrid how to achieve this...
My aspx code is
<asp:DataGrid ID="dg1" runat="server">
<Columns>
<asp:TemplateColumn HeaderText="select">
<ItemTemplate>
<asp:CheckBox runat="server" ID="chkD" />
</ItemTemplate>
</asp:TemplateColumn>
</Columns>
</asp:DataGrid>
I have 2 grids gvParent & gvChild I would like to filter gvChild when a row is selected in gvParent the linking fields are contractNo
I added a column for selecting:
<asp:TemplateField ShowHeader="False">
<ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False" CommandName="Select"
OnClick="LinkButton1_Click" Text="Select"></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
I know how to handle the filtering of the grid (create a criteria and set to rowfilter of the dataview) But, I dont know how to get the value of the column of the selected row.

I cant seem to figure out what is wrong with my check digit code!
At times, it produces 2 length check digit values

1277532495000110 <-- check digit is double value???????
1277534649000110 <-- check digit is double value???????
127753185300011 <-- good!
127753208500019 <-- good!
