Dropdown List in Gridview - While saving the record in gridview the droppdown selected index are cha



I am developing page for maintaing employee record using Visual Studio 2008, MS SQL server 2005.

I am able to fetch and display all the employee information in gridview, the gridview have the dropdown list to display the employee type [ Part Time, Full Time, Permanent , Contract ], in the item template i am having dropdown list. IN the dropdown list i am displaying this.

But While saving the record in gridview the droppdown selected index are changed to 0 of other dropdown list.

the user may be change the dropdown value from permanent to contract, or so. but while click on the save button in gridview, all the previous selection are gone, and always showing the first record of dropdown list. I know this is happening because we are doing dropdown list bind on onRowDataBound.

But i want to retain all the user selection in gridview, please help me how to do this.

thanks in advance.

Gridview with a dropdown list for editing


Hello. I am working through Scott Mitchell's ASP.Net in 24 hours book. I am finishing the photo album project.

I have a GridView that retrieves a list of uploaded photo rows for the logged-in user.
The GridView is for editing and deleting rows.

The photo Category field in the Gridview is a dropdown list. The text entry field was deleted after converting this field to a Template.

Like the uploaded photos, these Categories are user-specific. They are created in another web page.

Users also have the option to select "none" for the category when they upload an image.

For the GridView:  The Category ID field's ItemTemplate and EditItemTemplate both have a " - None - " choice added to them.

I am getting this error:

'pictureReadOnlyCategories' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value


Note: The ID for the ItemTemplate for that dropdown list is the ID listed above in the error: "pictureReadOnlyCategories".


Am I missing some step in this process of changing a GridViews text field to a dropdown that can be used for editing? I went through the book's instructions three times.

Here is my code for the dropdown list and a screenshot of the Design

How to disable fields in a GridView when you change the listbox options?

 Hi all I am trying to apply the same logic I applied to a FormView. Here is what I do:I have a DropDownListBox as one of my FormView fields and when I choose a specific option the fields inside my FormView are enabled/disabled according to the options chosen. Well I havent been able to apply that concept to a GridView. Here is my code to the FormView:protected void ItemFormView_DataBound(object sender, EventArgs e) { DropDownList ddlConfigType = ItemFormView.FindControl("ddlConfigTypes") as DropDownList; if (ddlConfigType != null) { if (ItemFormView.CurrentMode == FormViewMode.Edit) { DisableNAFields_EditMode(ddlConfigType.SelectedItem.Text); } } }private void DisableNAFields_EditMode(string configType) { TextBox txtboxScope = ItemFormView.FindControl("txtboxScope") as TextBox; if (configType == "registry") { txtboxScope.Enabled = false; } } Is there a GridView mode enumeration? How do I achieve the same goal? Thank you

How to Capture a DropDownList Selected Index Change Event

I have a gridview that receives data based on selection from a primary dropdownlist object. Works.
