[Code]....
I have created an asp.net customizable gridview where user will be able to add and delete data. Now I face some proplem with this gridview. now I want to add a dropdown list (which is dynamically bind with database) inside the grid. I created code and it bind well. when the page is post back previous selected dropdown list value lose and set to selectedIndex=0; For this reason I used if(!page.Ispostback) and put the dropdown binding code inside this. Here I faced a problem. The problem is when I want to add data inside grid the dropdownlist missin bind. How can I overcome this problem? For your kind observation I given entire code below:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
CellPadding="4" ForeColor="#333333" GridLines="None"
onrowdeleting="GridView1_RowDeleting"
onrowdatabound="GridView1_RowDataBound">
<RowStyle BackColor="#EFF3FB" />
<Columns>
<asp:TemplateField HeaderText="SL">
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("RowNumber") %>'></asp:Label>
</ItemTemplate>

View 4 RepliesI'm having a problem with using a dropdown to filter the contents of another drop down. The basic idea is:
Dropdown 1 = CountryList (Column1)
Dropdown 2 = StateList (Column2)
I read the contents of a CSV file and populate the gridview. The user then visually verifies that the data is valid and proceeds to upload to the database. To do some testing, i have intentionally changed spellings of country names so they DO NOT match the countrylist which the grid view then flags with a different background indicating bad data. The user then edits the gridview. The Country and state columns then show a drop down control populated with the country list and filtered states list based on countryID.
Here's the ASP.NET ASPX Source for the section of code that is dealing with the gridview
[Code]....
Here's the section of VB Code behind that deals with handling the "RowEditing", specifically the binding of the dropdowns
[Code]....
The proglem is that these dropdowns are ment to easily fix minor errors in data. When i intentionally changed the spelling of "Canada" to Canadaa", this has no corresponding CountryID in the table and the ddlEdtStateID Dropdown's datasource filter does not work. I tried setting the datasource to nothing if a valid CountryID was not there and then i tried to use the SelectedIndexChanged event for the ddlEditCountryID to programmatically set the datasourceID for ddlEditStateID but when i try using CType(FindControl("ddlEdtStateID"), DropDownList) to set the DataSourceID, it does not find the control.
If the Country does not exist, then i just want the stateslist dropdown to say "select a country" but when a valid country is selected, it should display the filtered list for that countryID. Right now, if bad data is entered for the country, then the program crashes when it tries to populate the state drop down. I want it to just say, select a country when the countryID is not valid.
Can i put gridview inside gridview and bind data to that inside grid?

I have a DropDownList inside the EditTemplateItem (if the user clicks edit) in a GridView.The DropDownList receives all available rows from the database. My problem is,if the user clicks Edit in the GridView to edit a row and opens the DropDownList Box the original item is not selected but the first one.That means the items are sorted. Have someone an idea how I can solve this issue that the right item / the original is selected if I change to edit mode of the grid view?

View 2 RepliesI am using an MS SQL Database with a table that has a DateTime column stored in it.
When I try to bind the data inside this table to a GridView and/or DataList the date shows up as (for example) '2010-03-03T00:00:00+01:00'.
In my GridView I tried to format that datetime by using the following 'BoundField' tag;
<asp:BoundField DataField="NewsDateEntered" HeaderText="Date Entered" DataFormatString = "{0:dd/MM/yyyy}" HtmlEncode="False" />
This is still wielding no results and I have tried to recreate the table and so on.
is it possible to bind gridview inside of usercontrol from content page, if so how?
