Please Help me in this matter.

var tv = document.getElementById('<%=
TVSectionContentsList.ClientID%>');
var treeNode = GetSelectedNodeEntity();
var treeNode = tv.getTreeNode(tv.selectedNodeIndex);
var val = treeNode.value;
var txt = treeNode.text;
FTB_API['<%=FreeTextBox1.ClientID%>'].InsertHtml('<span id=' + val + '>' + txt + '</span>');

ya sure.........this is the code....

<asp:GridView ID="gvMenuCategory" runat="server" AutoGenerateColumns="False" AllowPaging="true"
AllowSorting="true" PageSize="3" CssClass="datatable"
OnPageIndexChanging="gvMenuCategory_PageIndexChanging"
onrowdatabound="gvMenuCategory_RowDataBound">
<HeaderStyle HorizontalAlign="Left" CssClass="head" />
<Columns>
<asp:BoundField HeaderText="Name" DataField="Name" ItemStyle-Width="30%" />
<asp:BoundField HeaderText="Description" ItemStyle-Width="60%" ItemStyle-Wrap="true"
DataField="Description" />
<asp:HyperLinkField Text="Edit" DataNavigateUrlFormatString="/Menu/MenuCategory.aspx?Restaurant&MenuCategoryID={0}"
DataNavigateUrlFields="MenuCategoryID" HeaderText="Edit"></asp:HyperLinkField>
</Columns>
<HeaderStyle BackColor="#6B696B" ForeColor="White" />
</asp:GridView>

hope u will get idea by this..............

use the itemtemplate instead of BoundField
like this one

<Columns>
<asp:BoundField HeaderText="Name" DataField="Name" ItemStyle-Width="30%" />
<asp:TemplateField >
<ItemTemplate>
<asp:Label id="lblDescription" Text='<%# Eval("Description") %>' />
</ItemTemplate>
</asp:TemplateField>
<asp:HyperLinkField Text="Edit" DataNavigateUrlFormatString="/Menu/MenuCategory.aspx?Restaurant&MenuCategoryID={0}"
DataNavigateUrlFields="MenuCategoryID" HeaderText="Edit"></asp:HyperLinkField>
</Columns>

Then use the RowDataBound event of your gridview

and code the following
protected void gvMenuCategory_RowDataBound(object sender, GridViewRowEventArgs e)
{
string fulldesc="";
if(e.Row.RowType==DataControlRowType.DataRow)
{
DataRowView dr= (DataRowView)e.Row.DataItem;
fulldesc=dr["Description"].ToString();

Label lbldesc = (Label)e.Row.FindControl("lblDescription");
lbldesc.Text = fulldesc.Substring(0, 19);

}
}

Hope this work for you

Hi Guys,

I am using MasterPage in VisualStudio2008.
Master page and content pages are working fine.

There are one problem is on header of Masterpage.
There are 5 flash buttons. Like HOME, PRODUCTS, DOWNLOADS etc...

When I am on home page this Flash Button [HOME] color is changing but when I am clicking PRODUCTS or any other flash button then this PRODUCTS button color is not changing its still changing HOME button color.
Page is redirecting but header buttons color is not changing.

Please let me know where I am wrong.

Thanks

Cant really say without looking athe code.
But if you ask me to make a wid guess than I would say that the events (probably mouse over?) on other buttons are also targeting home button.

I set up ImageUrl in design time to some image in the App_Data and it is visible in the Design tab in .aspx file.
But as I start the project with F5 to debug, the image is not visible.
Also the other images file paths I set to ImageUrl property are not visible at run time.
What is wrong with Image control?

Nothing Wrong with it Smile | :)

You are putting Images in wrong folder. App_Data is not used for that. Use Separeate Folder (Create Images) and put the images on that folder and Try to access from there.

Thanks.

Why is it not suitable for images? Are there some standard folders for that purpouse?

There are:

App_Code
App_GlobalResources
App_LocalResources
App_WebReferences
App_Data
App_Browsers
App_Themes

From the coding standards point of view, which one is the right?
Actually I put all images into App_Data\Images and then just switch ImageUrl to any of them. But they do not appear at run-time.

Are these folders some kind of forbidden ones to access from web page by means of web controls?

App_Data is used to access the SQL database(or Access if you like more pain Smile | :)

You should rather create a new folder, lets say Images and put your image file these.

I did and it worked, but what is the reason to avoid App_* folders?
