I have a gridview that receives data based on selection from a primary dropdownlist object. Works.
Within the gridview, there is a dropdownlist whose selected index is based on the query from the primary dropdownlist. Works.
Problem.
How do I force the used to change whatever value that the dropdownlist contains after they make their initial selection from the primary dropdownlist; except the default value of "make a selection".
Gridview, contains a checkbox which drives whether a selected row is inserted into the data base. The databind in done using an ObjectDataSource on the presentation page, not in the code behind.

View 1 RepliesI am developing a web site to display some data that is inside a database. To do this I've created an ASPX web page that opens a connection to a database and retrieves the desired data. After that it populates an asp:table object dynamically.
The problem is that some of the fields that are retrieved from the database are too large to be displayed on the web page, so I decided to make a popup that would be able to display just the desired field.
To do this I've added a button to the asp:table so that when the user clicks it the popup would appear with the contents of the field. However what is happening is that when the user clicks on the button, the page just gets reloaded and the Click event handler is never called.
Below is the code in which I add the button to a TableCell, and the TableCell to the TableRow collection:
[Code]....
note that the popupHandler is a delegate to the function below. I am using it as a the Click event handler for testing purposes.
[Code]....
Also you should be aware that the table is only populated when the user clicks on a "Query" button inside the main ASPX web page, this means that I only populate the table after the PageLoad event has occurred.

View 1 RepliesHow do I get row index value in gridview on current row after I insert value in textbox in that gridview?
I have a function textbox1_textchanged() on the textbox.
I have a simple query based on the index changed event of a dropdownlist in ASP.NET. The scenario is i have a dropdown list bearing a collection of items (say ONE, TWO, THREE, FOUR, FIVE) with the default value selected as 'ONE'. Now, when the client changes the index (say the client selects 'TWO'), a confirmation box is prompted asking 'Are you sure want to change the index?' with the buttons YES & NO. Now, the problem is, if YES button is clicked then its working fine as the index is changed. But when NO button is clicked in the confirmation box, I do not want the index to be changed to 'TWO' and it should be holding the previously selected value which was 'ONE'. How can I do this? For which event should I write the code, as I cant think of writing the code for the IndexChanged event because here the index change has already occured and since there is no 'IndexChanging' event in ASP.NET, where shall i write the code

View 9 RepliesI am having a label to show success message during the successfully save.
I am having a drop down with the name "Technology".
During on selected index change event of the drop down, i am binding another drop down with the name "Resources".
When the Button is clicked, i am showing the "success message" and on click event of the drop down, i am clearing the message by using the java script.
function ClearErrorMessage() {
document.getElementById('ctl00_ContentPlaceHolder1_lblMessage').innerHTML = '';
}
But when i change the drop down, the message gets reappeared.
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 want change the background row when I press on Update LinkButton in side grid view Please say to me what is wrong in this code I do it code but the background changed just in put C# word that means it's static on C# but I want when you do any value and updated it the result will be changed the background color:
