Forms Data Controls :: How To Find And Assign A Value Of Something To A Label Nested In DataList

Aug 10, 2010

I am trying to find the text property of a label that is nested within a DataList within a FormView. The FormView and the DataList have different datasources.

What I actuallt need to do specifially is assign the number of rows in the DataList to the Label in the DataList. I used the code below to find it but it keeps giving me an error about not finding the object;

Forms Data Controls :: Find A Value In A Nested Datalist?

Jun 21, 2010

I have two datalists. Data list 1 shows regions; data list 2 is nested in datalist 1 and shows the cities in those regions. The two datalists bind ok.

However, I'm trying to call a click event from the nested data list (2) so that when clicked, the cityID nested in datalist 2 will appear in a label.

Here is a simplified version of the code.

Forms Data Controls :: Looking For Clean Approach To Building Nested Datalist Or Nested Gridview

Jun 17, 2010

Is there a better, cleaner way to do this in ASP.NET 2.0?

An ASP.NET 2.0 page displays a datalist of records. Each record can have many dates, so the dates are in a nested gridview (I chose a gridview over a datalist here because we want to be able to delete a date and this is easier done in a gridview). The parent record can never be deleted.

The display works fine: the nested gridview gets its datasource during the parent datalist's OnItemDataBound event.

The problem: the nested gridview's delete function. The date gets deleted without a problem (handled in the OnRowDeleting event), but somehow the redisplay is untying all the other nested gridviews from their datasources. The delete does not appear to cause a page postback, so I don't know how the other nested gridviews are losing their datasources.

Forms Data Controls :: Assign Datalist Value To Variable

Jul 8, 2010

I have a Datalist and when a button is clicked I would like to send the values of the fields to a new page to fill some text boxes. What is the best way to do this. I had thought that since the DataList had itemtemplates that were labels I could reference them like regular labels ( str = Label1.text ). That isn't working. I was just going to send the values through a query string. Which I have an example of that, unless there is a better way.

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..
