It may complete faster - I assume that when the server is retrieving the recordset its not fully utilized, and so probably could benefit from starting to databind the early records that come through.

Not sure if this would actually be worth doing - but the potential is there.

I'm talking about fetching the data async on the server for a single page execution. I just realised you might be talking about having the page be rendered, sent to the client and then asked to fetch the recordset. This might look smooth to the client, but the total time will undoubtably be greater - due to the amount of processing done client side (in javascript).

PHP probably does have some kind of async support - but I'm not a PHP developer.

you need to publish your code which will generate assemblies for your code.

Totaly depends where are you writing the suggested lines
Could you provide the code
after binding the datasource just insert select string at 0 index it's simple

Thanks and Regards

If you are using SQLDataSource, I think you'll need to add the code provided in the Databound event of the dropdownlist

sure, all you need is to insert the string at the particular index after the data binding have occured.With the databound event you can trap the binding process.

If DataSet.Tables.Count > 0 Then

dtTable = DataSet.Tables(0)

objList = CType(drpDropDown, System.Web.UI.WebControls.DropDownList)

With objList

.Items.Clear()

.DataValueField = "value"

.DataTextField = "text"

dtRow = dtTable.NewRow()

dtRow(0) = -1

dtRow(1) = "--Select--"

dtTable.Rows.InsertAt(dtRow, 0)

.DataSource = DataSet

.DataBind()
End With

Hi all,

I m newbie to Asp.net(Vb) Sleepy | :zzz:

, In my application i want to formt grid view using html code like this Laugh | :laugh:

<br />
 Dim dt As New DataTable<br />
        Dim dc As New DataColumn<br />
<br />
        dc.DataType = GetType(String)<br />
        dc.ColumnName = "Description"<br />
<br />
        dt.Columns.Add(dc)<br />
<br />
        Dim dr As DataRow<br />
        dr = dt.NewRow<br />
<br />
        dr.Item("Description") = "<html><body><font color=red>Text will goes here</font></body></html>"<br />
        dt.Rows.Add(dr)<br />
<br />
        Me.GridView2.DataSource = dt<br />
        Me.GridView2.DataBind()<br />

but the DataRow doesn't have the text property so it doesn't treat html as code it display as it is Mad | :mad:

I know i can user gridview.row(0).item(0).text to do it but it becomes difficult to manage paging in gridview Cry | :((

I hope someone will understand my problem so i m looking forward for your resoponse Roll eyes | :rolleyes:

Its something you have to do with the GridViewColumn's property.

You have set the HtmlEncode property to False.

Use the following code

objDataSet will have the set of records which are retrived using select query.

ddlBestFor.DataValueField = objDataSet.Tables[0].Columns[1].ToString();
ddlBestFor.DataTextField = objDataSet.Tables[0].Columns[0].ToString();
ddlBestFor.DataSource = objDataSet.Tables[0];
ddlBestFor.DataBind();
ddlBestFor.Items.Insert(0, "Select");
