Ultrawebgrid Search Problem
posted

Hi Team,

I have a search button on the form which is used to search the database and  then dispalys data in the webgird. And I have checkbox colum in my ultrawebgrid which is  used to identify which row is selected.

Individually they works fine ,but after the seach button clicked the selected row id which idendtified by the checkbox is not right .It gives me the id from the begining of the whole the datebase, not form the searched data.  Will any one help me? I will give my sample colde.

Thank in adavace.

    Hi sunqy1212,

     

    I have been looking into the behavior that you have described and I could suggest you to clear the grid’s DataSourceID using the following syntax: UltraWebGrid1.DataSourceID = null, and after setting the new data source on BtnSearch_Click, call DataBind method:

     

            DataTable dt = new DataTable();

            dt = GetDataTable(strSql, "UserData");

            this.UltraWebGrid1.DataSourceID = null;

            this.UltraWebGrid1.DataSource = dt;

            UltraWebGrid1.DataBind();

     

    Please let me know if this helps.
