Thanks for the reply. I have to write the recursive function to show the output as treeview.

What are you trying to do? Where is your code?

Thanks for the reply. I have to write the recursive function to show the output as treeview.
I have to generate the script based on the datatable rows. My normal function works fine if it has only one level but now in my datatable there can be more levels and for this I need to write recursive function. Following is the code:

private void FillValues(DataTable dtFinal)
{
int intChildRowCnt = 0;
StringBuilder strDBScript = new StringBuilder("");
strDBScript.Append("<script language='javascript' type='text/javascript'>");
// Create wsGrid Instance
strDBScript.Append("var m_wsGridCtrl = new jsTreeGridCtrl();");
// Param1: width
// Param2: OnMouseOver Color
//strDBScript += "m_wsGridCtrl.initializeDocument(1000, '#FF9999');";
strDBScript.Append("m_wsGridCtrl.initializeDocument(1000, '#8A9FFF');");
// Titles
// Param1: Text
// Param2: Width

// DataTable dtFinal = GetDataTable();
Int32 intColCnt;
if (dtFinal.Rows.Count > 0)
{
for (intColCnt = 0; intColCnt <= dtFinal.Columns.Count - 1; intColCnt++)
{
if (intColCnt == 0)
{
strDBScript.Append("m_wsGridCtrl.InsTab('Show All', '30');");
}
else if (intColCnt == 2)
{

}
else if (intColCnt == 1)
{
strDBScript.Append("m_wsGridCtrl.InsTab('" + dtFinal.Columns[intColCnt].ColumnName + "', '50');");
}
else
{
strDBScript.Append("m_wsGridCtrl.InsTab('" + dtFinal.Columns[intColCnt].ColumnName + "', '20');");
}
}
DataRow[] foundParent;
DataRow[] foundChild;
foundParent = dtFinal.Select("PresentationParentSpecElementID Is null");

if (foundParent.GetUpperBound(0) > 0)
{
for (Int32 intRowCnt = 0; intRowCnt <= foundParent.GetUpperBound(0); intRowCnt++)
{
foundChild = dtFinal.Select("PresentationParentSpecElementID=" + foundParent[intRowCnt]["SpecElementID"]);

if (foundChild.GetUpperBound(0) > 0)
{
strDBScript.Append("var iItem" + intRowCnt + "=");
}

strDBScript.Append("m_wsGridCtrl.InsItem(null, '");
for (intColCnt = 0; intColCnt <= dtFinal.Columns.Count - 1; intColCnt++)
{
if (intColCnt == 0 || intColCnt == 2)
{
}
else
{
strDBScript.Append(foundParent[intRowCnt][intColCnt] + ";");
}
}
strDBScript.Append("');");

for (intChildRowCnt = 0; intChildRowCnt <= foundChild.GetUpperBound(0) - 1; intChildRowCnt++)
{
strDBScript.Append("m_wsGridCtrl.InsItem(iItem" + intRowCnt + ",'");
for (intColCnt = 0; intColCnt <= dtFinal.Columns.Count - 1; intColCnt++)
{
if (intColCnt == 0 || intColCnt == 2)
{
}
else
{
strDBScript.Append(foundChild[intChildRowCnt][intColCnt] + ";"); }
}
strDBScript.Append("');");
}

}
}
else
{
foreach (DataRow row in dtFinal.Rows)
{
strDBScript.Append("m_wsGridCtrl.InsItem(null, '");
for (intColCnt = 0; intColCnt <= dtFinal.Columns.Count - 1; intColCnt++)
{
if (intColCnt == 0 || intColCnt == 2)
{
}
else
{
strDBScript.Append(row[intColCnt] + ";");
}
}
strDBScript.Append("');");
}
}

strDBScript.Append("m_wsGridCtrl.GenerateCode();");
strDBScript.Append("m_wsGridCtrl.RecudeAllTree();");
strDBScript.Append("</script>");

ClientScript.RegisterClientScriptBlock(this.GetType(), "onload", strDBScript.ToString()); }
}

Now I need to convert this in recursive function..

Please help me...

Thanks again...

You could consider using the SQLXML managed classes to return the results of your query as an XML document. I don't know what treeview control you are using (some 3rd party / bespoke component) but if you use the TreeView control in ASP.NET 2.0 then you can bind the control to an XML datasource. You then don't have the hassle of writing your own population routine.

How to pass url of upload control in to session varibles

Thanks for the reply. I have to use Treeview only as I have to show the data as TreeGird (TreeView Inside GridView) and so I am generating script for the same which builds the TreeGrid control.

Please help me with this...

If your question is of such high priority, why are you not paying for assistance instead of coming to a site where people offer their help for free?

Anyway, you haven't expressed the problem intelligibly so I don't understand what you are trying to do.

You can take the file name to session easily like following code

Session["FileName"] = FileUpload1.PostedFile.FileName

But this won't help you to show the image on next page until it is not uploaded. This filename gives client path for image. This can't be loaded using a server side scripting.

Are you looking for an image preview ? Then try using some javascript and show the image.

if exists(select CombinationId from tblItemsIdComposition where Id = @itemid and SubId = @subitemid and SSubId = @ssubitemid )
begin
select @combinationid = CombinationId from tblItemsIdComposition where Id = @itemid and SubId = @subitemid and SSubId = @ssubitemid

end

can i improve it a little bit?

You should ask questions like this in the SQL forum - it has nothing to do with ASP.NET.

Hi Sonia,
Here u throw same query twice, which is not necessary.. instead u can write like this:

select @combinationid = CombinationId from tblItemsIdComposition where Id = @itemid and SubId = @subitemid and SSubId = @ssubitemid

-- @combinationid is null implicitly means that record does not exist!!
if @combinationid is null
begin
select 'not found'
end
else
begin
select 'found'
end

Hope this helps

Mitesh

what about

@combinationid = isnull(select CombinationId from tblItemsIdComposition where Id = @itemid and SubId = @subitemid and SSubId = @ssubitemid,0)

Hope its correct!!!

You could use a RegularExpressionValidatorControl and link it to your text box to constrain its input.

What characters do you want to allow/exclude? By way of example, the following regular expression will match if a string contains only alphanumeric characters, apostrophes, full stops and spaces.

^[a-zA-Z0-9'.\s]*$
