How can i check on a fast way (less code) if a dropdownlist has a item called 2008 ? Right now i do this:
drpBouwjaar.Items.FindByValue("2008").Selected = true;
But if the item doesn't exsits i get an error.
I use a ItemDataBound for a repeater.But i use 2 kinds of linq querys to bind it.Some of them has a MerkID, and some doesnt have this item.So its easy i need to do this:
if(e.Item.DataItem.Contains("MerkID"))
{
//Code for linq query 1
} [code]...
So of course the if selection doesnt work, but how can i do that? I already tryed this:
DataRowView drv = (DataRowView)e.Item.DataItem; if (drv.Row.Table.Columns.Contains("MerkID"))
But that doenst work because he cant convert it to a datarowview because its a linq class.So what to do? Right now i use a try and catch, but there are better solutions i guess...
I have a project that queries a set of times from a database and uses these entries to populate a dropdownlist. Once the page is loaded, the user can select one of the items in the DropDownList. When the "Save" button is clicked, the Selected item value is returned to the [HttpPost] version of the controller action. This item is then stored into session. If the system returns to the page containing the dropdown, I want the saved Value to be selected in the DropDownList. What actually happens is that the DropDownList is always set to be the first item in the list.
Database Table: This data has been imported using Link to SQL
[code]....
I bind dropdownlist in my page
protected void Page_Load(object sender, EventArgs e) {
BindDropDownList(DDL1, "city1", "name", "ID");
DDL1.Items.Insert(0, new ListItem("select city", "0"));
}
And SP
LTER procedure [dbo].[city1]
as
begin
select id,Name
from city
end
And design code
<asp:DropDownList ID="DDL2" runat="server" CssClass="daddsd">
</asp:DropDownList>
And here is imagebutton code that when click on it update data into table
protected void ImageButton_Click1(object sender, ImageClickEventArgs e) {
string data = Server.UrlDecode(Request.QueryString["BehCode2"]);
SqlCommand _cmd = new SqlCommand("insertinfo", _cn);
_cmd.CommandType = CommandType.StoredProcedure;
_cn.Open();
[Code] ....
Here when i click on button it insert all data into table but it didn't insert my selected item from dropdownlist it insert select city that i define in page_load
DDL1.Items.Insert(0, new ListItem("select city", "0"));
And when i delete this code from page load it insert in table first row of my table it didn't insert my selected item from dropdown list.

I have a DropDownList in a template column of a GridView control. The GridView is bound to a list of objects. Each object has a property of type int which corresponds to a value in one of the DropDownLists ListItems. I could set the selected item programatically by adding a DataBind event to the drop down, but I'm wondering if there's a way to set the selected item by using a code block in the aspx markup.
