DropDownList FindByValue Problem

My first DDL works great:

        String BrandID = Request.QueryString["BrandID"];

        ddlChoseBrand.Items.FindByValue(BrandID).Selected = true;

My two other dosent work, how shall I write the code correct?

        CategoryAccess.GetDllInfo(id);

        String ModelID;
        String CategoryID;

        ddlChoseModel.Items.FindByValue(ModelID).Selected = true;
        ddlChoseCategory.Items.FindByValue(CategoryID).Selected = true;

In GetDllInfo I simply get witch one thats going to be selected. So the problem is that I dont know how to write the code correct.

I had this problem too with ddl, but mine was comparing with database. find that .Trim() actually solves the problem.

EG:

ddlChoseCategory.Items.FindByValue(CategoryID.Trim()).Selected = true;

good luck for people who have the same problem as I am. :D

I had the same problem yesterday, It seems like .selected = true doesn't always work as We suppose to..

here is a little workaround you can use instead.

ListItem myitem = ddlChoseModel.Items.FindByValue(ModelID);
ddlChoseModel.SelectedValue = myitem.Value;

peerin mind that selectedValue is a Get property not Get/Set .. but It did worked great with me :D

Good luck :)
