Customize Paging

[111111222222]

Hi All

I have a grid view. I added a drop down list on top of page to select number of records in grid view. Somehow I am unable to do that ...

Here is my code... Could some one please help me out?

Thanks in advance
[code=asp]
<asp:DropDownLi st ID="ddlSize" runat="server" OnSelectedIndex Changed="ddl_Se lectedIndexChan ged">
<asp:ListItem Value="10">10</asp:ListItem>
<asp:ListItem Value="20">20</asp:ListItem>
<asp:ListItem Value="30">30</asp:ListItem>
</asp:DropDownLis t>
[/code]
[code=cpp]
protected void ddl_SelectedInd exChanged(objec t sender, EventArgs e)
{
gv.PageSize = ddlPageSize.Sel ectedValue;
gv.DataBind();
}[/code]

Try to use the SelectedItem property of the ddl.

gv.PageSize = [B]ddlPageSize.SelectedItem[/B];

Also, plz wrap your code in the [code] BLOCKS(Click the # symbol available on the extreme right of your editor window), which makes your post easy to read.

Thanks Ram!!!

I changed ddl property to selected item. I am getting a build error like

Cannot implicitly convert System.Web.UI.W ebControls.List Item to 'int'.

I am new to .Net. Could you give more suggestions please...

Try this:

gv.PageSize = ddlPageSize.SelectedItem.Value.ToInt()

[Ramk]

Try this:

gv.PageSize = ddlPageSize.SelectedItem.Value.ToInt()

codegecko

This will give compilation error.ToInt method doesn't exist in String class.

Use Convert class as follows.

Convert.ToInt32(ddlSize.SelectedItem.Value)

In addition to Ramk's suggestion, could use the Integer.Parse method:
[code=cpp]
gv.PageSize = Integer.Parse(d dlPageSize.Sele ctedItem.Value) ;
[/code]

After I changed it like this, was able to bind drop down value to grid view.

 gvDetails.PageSize = Convert.ToInt32(ddlPageSize.SelectedValue);
