View 4 RepliesI would like to find controls in the detailsview control placed in the EmptyData Template of the gridview. I am trying to create Insert new record for the gridview control.
1. If there are existing records in the table - works fine and sets my two values: I placed Detailsview and Insert Button in the footer of the gridview. I needed to set the values of two fields. When I click on the Insert button it saves new record and sets the field with the value (code attached - works fine). I also have a popup extender that opens detailsview - this works just fine.
2, If ther are not records in the table - saves record but cannot find and set controls on the detailsview Same thing setup in the EmptyData Template. The record is saved but I cannot Find and set the field value on the control.
1. Link button (on click) in the gridview footer (works fine)
protected void LinkButton1_Click1(object sender, EventArgs e)
{
string zupa1;
zupa1 = ddlSelectEmployee.SelectedValue;
try
{
DetailsView zupa = (DetailsView)gvTraining4.FooterRow.FindControl("DetailsView1"); TextBox zupa2 = (TextBox) zupa.FindControl("txtInsertEmployee");
zupa2.Text = zupa1;
}
catch
{
}
DetailsView dettraining = (DetailsView)gvTraining4.FooterRow.FindControl("DetailsView1");
TextBox training = (TextBox) dettraining.FindControl("txtTrainingType");
training.Text = "4";
}
2. EmptyDataTemplate.FindControl - can save record but cannot access txtInsertEmployee and txtTrainingType
DetailsView zupa = (DetailsView)gvTraining4.EmptyDataTemplate.FindControl("DetailsView1");TextBox
zupa2 = (TextBox)zupa.FindControl("txtInsertEmployee");TextBox
training = (TextBox)dettraining.FindControl("txtTrainingType");"4";
I tried to get the LoginName control inside LoginView LoggedIn template , despite several methods, the code still could not work.
I wished to change the default username to the customer name.

<div style="text-align: right; margin-right: 5px ">
<asp:LoginStatus ID="LoginStatus1" runat="server" LogoutPageUrl="~/Home.aspx" Font-Underline="True" />
</div></div>
</LoggedInTemplate>
</asp:LoginView>
At the code behind :
protected void Login1_LoggedIn(object sender, EventArgs e) {
LoginName loginName = LoginView1.FindControl("LoginName1") as LoginName;
Response.Write(loginName.ToString()); //for now I used Response.Write for testing purposes
}

I have 3 buttons that change the Information being displayed in my Gridview (Previous, Today, Forward). Now management wants to SUM the Date's information by column, I have figured out how to do this by changing the BoundField to a TemplateField and then add a FooterTemplate with a SQL DataSource. When I Press either the Previous or Forward button the data does not change in my Sum'd Footer column.

I've been working with this tutorial:

It's basically how to create an editable gridview.
I've got it up and working, but I need to change the width/height of the textboxes when the gridview is in edit mode.
The problem is, when the textboxes are rendered, they don't have ID's so I can't use FindControl to modify the textboxes.
Adding textboxes in the template items just created an independant - textbox that doesn't do anything.
My question is, how can I find these textboxes & change their height/widths, or how can I find these textboxes & assign ID's to them...so I can modify their height/widths?
Here's a snippet of what I've been playing with....haven't had any luck though...I'm probably way off:
