Forms Data Controls :: Changing A GridView's ItemTemplate Label Text Dynamically

May 7, 2010

I'm trying to change the text of a GridView label in an ItemTemplate and I am having some issues. I searched all over and can't find a solution. This is what I am trying to do...

I have a GridView that has a comment field. Normally when the page is rendered the comment field is truncated using a truncate class that limits field length. The full contents can be displayed in a tooltip when the comment field is hovered over. That part works fine.

I also have an export to Excel class that will take the Gridview and export it to Excel and that part works fine as well...

Now the issue... Because of the truncated field, when I do an export it will export exactly what is in that field, the truncated version of a comment. When the export button is clicked I need to change the .text value of the label that is in the GridView ItemTemplate

From this truncated version...


And then back again after the export routine is complete.

I have accessed the contents of a label before using FindControl but never set a value, is this possible? Also, I have captured what is in the comment field on RowDataBound but by that time, it is already truncated.

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.

Jan 27, 2011

I have a web page that has a repeater bound to a data source. I beed to change a label inside the repeater based on the data that is in each repeater item. For instance, for the first item it might be one thing, and for the next item the label may be something else. I am currently doing some processing in the prerender event, but I don't know if I can or how to access the data source fields there. Where and how do I get access to the data in each item so I can change the label text?

Forms Data Controls :: Dynamically Populate A Gridview Itemtemplate?

Jul 14, 2010

I have a page with a gridview in which I currently populate with a stored procedure. There is an additional column I want to add to the gridview and populate (either dynamically or with a sqldatasource). Though I'm not sure how? If I create it dynamically, I don't know which gridview event to use (I would guess the rowcreated event)? Which is better or is there a better alternative to what I've proposed?

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>

Forms Data Controls :: Setting Text Programmatically In ItemTemplate Of Gridview Does Not Show

Mar 7, 2010

The problem is this: I am writing a system to show helptexts on certain labels. So in the PageLoad I recursively iterate all controls and save those with a certain tag. So far so good.

On the PreRenderComplete I iterate the controls and set their text property. The strange this is that the labels in ItemTemplate don't get the new text. The PreRenderComplete fires after the DataBound event of the gridview, the label gets found perfectly, in the end it has the new text, but in the page it's still the old text.

I hope I don't need the Row_Databinding event of the gridview, since I want to put all the functionality in an extender class with as little custom work as possible.

How To Get Text From A Label In A DataList ItemTemplate

Apr 13, 2010

I use Visual Web Developer 2008 Express.I have Label1 in a DataList ItemTemplate. I wish to use a button to get the text from that label and add it to text in TextBox1 which is elsewhere on the page.I know how to do this from a standard label on a ASP.NET web page but cannot work out how to get the text from a label inside a DataList ItemTemplate.

HTML Code:
Protected Sub submit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles submit.Click
TextBox1.Text = TextBox1.Text & " " & DataList1.ItemTemplates.ItemTemplate.Label2.Text
End Sub
I thought that because DataList1.ItemTemplates.ItemTemplate.Label2 - System.Web.UI.WebControls.Label - is what is written in the properties window header when I select the label in the DataList template.

Forms Data Controls :: Label From Dropdownlist In Itemtemplate?

Nov 25, 2010

I have a dropdownlist - ddlGroupName. Next to it, I have a Label - lblGroupName. The dropdownlist is bound to an SQL table, and displays the appropriate group depending on the primary key (contracters, suppliers, etc etc). When the page loads, I want the Label to display whatever is in the dropdownlist, then I can hide the dropdownlist and am just left with the label. I was using "lblGroupName.Text = ddlGroupName.SelectedItem.Text;", but intellisense doesn't seem to acknowledge the controls when they're in an ItemTemplate.

Forms Data Controls :: Getting Text Value From Label In A Gridview?

Apr 16, 2010

I'm trying to get the text value of a label when that row is selected in my gridview. The label's text is databound. Originally when I used the <ASP:BoundField /> I retrieved the data by using this syntax "Server.HtmlDecode(row.Cells[1].Text )" when an "onrowcommand" event is triggered. My question is what is the syntax to retrieve the text value of this label if I am using a template field in my gridview. The code for my label is below.
