OK, I have dropdownlist bound to a datasource with the following query:
"select ccid, buname from tblCostcenter;"
I have the dropdownlist set to show only the "buname" column.
Now, when the user makes a selection for my dropdown, I want to grab only the selected value of the "ccid" column - even though "ccid" is not set as the text or value for the dropdown.
I have a situation where i need to update my Dropdownlist templatefield inside a GridView....but only for a specific cell. I have seen codes like this to loop through the whole GridView and update every rows in a specific column, but how do i do it if i only want to update one specific cell ? (If i know the index information of the cell, for example, I know i want to update the dropdownlist on Column 3 and Row 2)
foreach (GridViewRow row in GridView1.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
this.WorkTypeDDL = ((DropDownList)row.FindControl("WorkTypeList"));
this.WorkTypeDDL.DataSource = AL;
this.WorkTypeDDL.DataBind();
//more codes blah blah blah//
}
}
its possible to use a DropDownList within the PagerTemplate to navigate to a specific record? I have been able to place the DropDownList outside of the FormView and PagerTemplate and make it work, however, I can't get it to work inside the PagerTemplate.

View 3 RepliesI'm trying to access and display certain data in my database using category ID's. I've added values to the links in a link list and I was to have the selected value as the one that determines the selection in the selection statement. For example, "SELECT [ID_key] AS ID_Key, [Title], [Source], [PublicationDate], [Url], [CatID] FROM [Newsarts] WHERE ([CatID] = Linklist1.SelectedValue)". I know Linklist1.SelectedValue doesn't work or it may work and I don't know how but I want to be able to use the value selected from the previous link. Is there a way?
Also, after all the data is displayed, I would like them to become links themselves. Basically, I want to choose a category, then choose an article in that category, and they hit the link to display the article's content.

CheckBox Passing a specific Value to an SQL Column the object I am trying to reach is to pass a value "true" via a checkbox nested inside a GridView to a SQL Table.
This is how the control is nested inside the GridView:

<asp:TemplateField >
<ItemTemplate>
<asp:CheckBox runat="server" />
</ItemTemplate>

View 5 RepliesHere's the background: I have a GridView with suggested meetings. A logged in member can view the suggested meetings and click button "Show" to view all suggested occasions for every meeting. What I want to do now is to hide button "Show" for a logged in member if she/he owns the meeting (i.e. is the one who suggested it = Session["memberID"]).
My problem is this: All buttons "Show" are visible. I want to hide button "Show" in those cases where Session["memberID"] is identical to dr[0]. 'ID' in the SQL statement is the ID of the meeting in the database and meetingID are the ID's of the meetings shown in the GridView.

I have a gridview that has both a select and an update statement. One of the cells is a date cell, and the other is for numerics only. Is there a way I can do this? At the moment, anything can be keyed into the cells and this results in an error as my update stored procedure expects a date value and a numeric value respectively.
