Hi
I have a web Form with one DropDownList which read it's data from a table.
and I have a button next to the DropDownList which run's an insert query to add a new item to the table.
Until now every thing is fine, but what I need now is to refresh the DropDownList and automatically select the new inserted item.

Hope to solve this problem
Thank you

Solution 1

Before insert the data to the database table, store the value in some variable

for ex.

<br />
Dim strNewValue$="New Data"<br />
<br />
InsertDatabase("New Data")  'Ur functionality to insert in database<br />
<br />
Dim dt as datatable = drpYourdropdown.datasource<br />
Dim dr as datarow<br />
dr=dt.NewRow()<br />
dr.Item(0)=strNewValue<br />
dt.add(dr)<br />
drpYourDropdown.datasource=dt<br />
drpYOurDropdown.databind()<br />
<br />

Try the above code...

Not exact but something like:
{
dynamic strNewValue = "New Data";

InsertDatabase("New Data");
//Ur functionality to insert in database

DataTable dt = drpYourdropdown.datasource;
DataRow dr = null;
dr = dt.NewRow();
dr[0] = strNewValue;
dt.Rows.Add(dr);
drpYourDropdown.datasource = dt;
drpYOurDropdown.databind();
}
