how do i use the dropdownlist in the Gridview.here is my requirement: i want to place one Drop down list in Grid view,when ever Gridview loads that dropdown must be fill.
i have a drop down list and a text box, inside a listview row (and this is a repeating layout). i populate each dropdownlist with same contents ( these contents/items come from a custom collection object).
i have added a required field validator in the listview's item template, that has its validation group = the validation group of the drop down list, and validates if the textbox is blank or not. this validation takes place on the selected index changed of the drop downlist for that row.
1. on selected index changed, EACH dropdownlist validates only its corressponding textbox perfectly (which is what i want)
but if i enter some text in one of the textboxes after doing 1, the dropdownlist for THAT particular row, assigns the correct value to the text entered. but for other rows (for which i changed their corresponding ddls to test the required field validation and for which the text boxes are still blank), their ddls by itself assign the values to the blank text without validating.
markup of code for listview is [Code]....
code behind for the ddl selected index changed is [Code]....
method GetIndexFromId retrieves index of the custom object inside a collection depending on the Id (which is a property) of the object.
i notice that the ddl selectedindexchanged is being hit as many number of times as many rows i change (i.e as many ddls in different rows i change to check the required field validation)
I have dropdown list I want to use the arror to click and control and select the value in the dropdown box , the first click select item1 .... How can I do that?
i've been learning MVC now for 2 days, but I still can't wrap my head around it. ASP.NET MVC feels like learning Mandrin Chinese. So, I understand Classic ASP.NET and using an N-Tier archetucture, but how would you apply that to MVC? I comprehend View (the UI), Controller (the pipeline to the Model and View), and the Model (where your code goes), but how would you apply an N-tier to MVC? Or, a replica of the DAL? Yeah, it might be a stupid question, but I am not understanding the Framework. Does anyone have an article(s) that cleared your understanding of MVC? Maybe I need to buy a book....
I have a Repeater control which contains asp:Button control in ItemTemplate.

For insance if there are three values in the dropdown there should be three columns in the list box with the heading as the values of the dropdownlist.for 5 it should be 5.
Also there are two additional columns which would be constant.
