Forms Data Controls :: Find And Set DetailsView Controls In Empty Data Template In Gridview

Oct 31, 2010

I 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;
DetailsView zupa = (DetailsView)gvTraining4.FooterRow.FindControl("DetailsView1"); TextBox zupa2 = (TextBox) zupa.FindControl("txtInsertEmployee");
zupa2.Text = zupa1;
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";

It was working for a while, can't figure out what I changed, but now says that object doesn't exist.

Forms Data Controls :: How To Access The Pageindex Gridview Property When Creating A Dynamic Template

Mar 15, 2011

I need to get access to the page index of the gridview so I can correctly get some data from a coresponding array to set the cell's contol properties correctly. Below is what I've got so far. The ExcelObject is a class that houses both the data read in from an sutomer submitted excel file and a matching 2 dimensional array of characteristics that I use in this case to set the CssClass property. My problem is that when I enable paging for the gridview I don't get the proper datasource row index when the data is read by the databinder.eval; what I'm getting is the current row of the gridview being generated.

Forms Data Controls :: C# Dynamic Gridview Using Template Field As Control?

Mar 31, 2010

I have a gridview and basically at page load I want it to display with an empty row. The first field in the gridview would be a template field containing a textbox. I wan't to be able to type in, for example, a product code ('abc'). This would be the parameter for the stored procedure and then the rest of the columns (40+ additional columns) in the gridview would populate with the rest of the data pertaining to that product code (i.e. price, unit of measure, etc.). In short the template field texbox is the control to bind the gridview.

After the row is populated I could click a button or link that would add that entire row to my gridview and then add another empty row where I could enter another product code... populate the row then add that row to the gridview. and so on...

Forms Data Controls :: Add Associated Control Id For Gridview Fotter Template Under Section 508?

Mar 15, 2011

I have gridview template field with 5 columns like First Name, Middle Name, P.No and Last Name. The grid has a list of people with a blank row at the bottom of the grid (in the footer) that allows the user to add a newperson to the list. I have added textbox under fotter template. i need to add associated control id for footer template text box.I have been asked to make the grid section 508 compliant. The requirement is that the column headers must have labels that referencethe text boxes in the footer row. On a normal web form it would look like this:

<label for="txtFirstName">First Name</label>
<asp:textbox id="txtFirstName" runat="server" />

This allows a text reader to figure out that the words "First Name" are associated with the text box "txtFirstName" and helps a blind personunderstand how to fill out the form.Now, back to my problem. I need to figure out a way to get the header of a Grid view template column to work the same way. The biggest problem is that I have no idea what the ClientID of the textbox will be.

Forms Data Controls :: EditItem Template Of Gridview - Template Field With Dropdown List - How To Make Current Value Sel

Dec 4, 2010

Setting up the editItem template of a gridview. I have a template field with a dropdown list for editing. When the gridview goes into edit mode the dropdown list is displayed with all the right options but the current value of the field (pre-editing) is not the selected value of the dropdown list? How do I make that happen? I have a couple fields where the editItem template will use a dropdown list and I'm sure a user will not realize those values have changed and they will just edit what they intended to edit and save the changes, inadvertently also making changes to other fields.
