Apr 15, 2010

I have a gridview being loaded via a Databind to a MembershipUserCollection

This works fine, but I need to add one more Column with data not found in the collection, so i added a TemplateField and a Label to my Gridview and in the TEXT prop of the label is where my problem is.

The function call is working, but my problem lies with providing the Datafield="UserName" value from the same row in GridView in the function call

This is my HTML for the GridView:

Forms Data Controls :: TemplateField Change Itemtemplate Label CSS Depending On Column Value For Each Row In Gridview?

Jan 28, 2011

I was wondering if anyone could help me. I have a template field which has four itemtemplates that each hold a label in a gridview. These labels are always constant with the same strings. What I want to do is change the css formatting of these four labels depending on the value of a column. So the css formatting would have to be done for each row, not the whole column. I bind the gridview to a dataaccesslayer so there is no sqldatasource on the page. Does anyone have any idea how to do this and where it would be done. I will have the dataview with the data sorted in the correct order. The actual column that is used to alter the CSS will not be in the gridview although I could assign it to the datakeyname if that makes it easier as the data is not sensitive.

Data Controls :: Assign Value To Label Inside TemplateField Of GridView From TextBox?

Jan 5, 2013

In my gridview, I have 6 columns. The first 5 columns are filled with data retrieved from database.In the 6th column I want to display a value from textbox from same form. The value should be displayed on the row next to last row of rest of the columns. So my last column (i.e.) 6th column will just have all the rows filled with the same value of the text box.

First 5 columns of grid will be filled by selecting the college name from dropdown.The last colum (Date) must be filled with the date that is given in the textbox.It can be even after button click event(date of attendence).

It can be done after button click event also..

Forms Data Controls :: Pulling The Value Of A TemplateField From A GridView?

Nov 23, 2010

I have a GridView, bound to a table (Meals) in a SqlDataSource.

Into that GridView, I have added a TemplateField, which contains a DropDownList (which displays the numbers 1 - 10, added manually; no Data Binding). And, I've added a ButtonField.

When I click the Button, I want the values of some of the GridView rows PLUS whatever value was selected in the DropDownList to be pulled out and stored in a second Sql table (Orders).

Pulling the rows bound to the SqlDataSource is easy but JavaScript is needed (I think) to pull the SelectedValue from the DropDownList. I understand women more than understand JavaScript (that's how little I know) and the code below has been kindly offered by another forum user who is at a loss, himself, now.

Here's the code and the error message I'm getting.

ASPX:

[Code]....

And here's the Code Behind:

[Code]....

No design time errors reported but here's the run time error:

Object reference not set to an instance of an object.

On the following line:

Line 28: if (row.RowType == DataControlRowType.DataRow)

Forms Data Controls :: TemplateField In Gridview Not Passing DataKey Value?

Feb 4, 2010

I'm relatively new to the VS environment. I'm using VS2010 Beta 2 with VB. I have a Gridview setup to pull a list of employees. Next to their name I have edit and delete icons. When I leave the icons as ButtonFields, they pass the DataKey value to my code behind perfectly. When I convert the ButtonFields to TemplateFields, they no longer pass the DataKey.

Forms Data Controls :: Get Datakey From Templatefield (dropdownlist) In Gridview

May 21, 2010

I have a gridview with a DropDownList (contained in a TemplateField). I have set the OnSelectedIndexChanged event to a function called "ddlAgent_SelectedIndexChanged" This allows me to aquire when a user has changed the value for the dropdownlist. What I need to do is persist this newly selected value to the database for the gridview record. The problem I'm having is how to I get the datakeyNames value for that row? See code below!

TemplateField source
<asp:TemplateField HeaderText="Agent">
<ItemTemplate>
<asp:DropDownList ID="ddlAgent" runat="server" AutoPostBack="False" OnSelectedIndexChanged="ddlAgent_SelectedIndexChanged">
</asp:DropDownList>
</ItemTemplate>
<ItemStyle HorizontalAlign="Center"></ItemStyle>
</asp:TemplateField>
ddlAgent_SelectedIndexChanged

Protected Sub ddlAgent_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)
Dim gvItems As DropDownList = CType(sender, DropDownList)
' Write the selected Agent ID to the Inquiry record.
'Dim ID As Integer = gvMaint.DataKeyNames(e.SelectedIndex).Value ' THIS FAILS BECAUSE
e.SelectedIndex is not part of System.EventArgs
End Sub

Forms Data Controls :: GridView BoundField Vs. TemplateField For Updating?

Feb 17, 2011

I have one two GridViews on a page. One Gridview uses BoundFields inside of the GridView and the Update statement works just fine. The other GridView utilizes TemplateFields due to the fact that Validation Expressions have to be used. I also want This GridView to be able to update the vlues when the user clicks on the Update link on the right side of the GridView. The GridView that uses the BoundFields updates just fine, but the GridView that uses TemplateFields will not update. I have checked and everything is correct other than this difference of BoundField and TemplateField.

Forms Data Controls :: Gridview - Dynamic Label - VB.NET - Change The Text Of The Label If Certain Criteria Is Reached?

Mar 15, 2010

I have Template fields configured for Gridview. The gridview is using an objectdatabsource to bind itself. I have the gridview configured to use Templatefields which then contain tables to display the information. This works fine.

My question is, is it possible to change the text of the label if certain criteria is reached. If "NumberOfDwellings" is 1 then change the label to read, "1 Dwelling". Where-as if NumberOfDwellings has more than one then it's "3 Dwellings".

<asp:Label ID="lbl_NumberOfDwellings" runat="server" Text='<%# Eval("NumberOfDwellings") & " Dwelling(s)" %> '></asp:Label>
