Re: GridView Pagination Problem - ASP.NET Discussion Boards

Is there a way in JavaScript to detect if the users press Shift + :?
The below code does not seem to work.

if (event.shiftKey && event.keyCode == 186)
event.keyCode = 9;

<html xmlns="http://www.w3.org/1999/xhtml" >

<input type=text id="txtBox" onkeyup="test()">
<script>
<!--
    function test() {
        if (document.getElementById("txtBox").value == "+") 
        {
            myalert();
        }
    }

    function myalert() 
    {
        alert("Shift++++ :)");
    }
//-->
</script> 
</html>

what will be happen you press the "shift" and "+"? Confused | :confused:

When I say Shift + : I mean when the user presses and holds the Shift key while pressing the Colon/Semi colon key.

Hello everybody.......

The data is stored in the MSSQL 2005 with raw fieldnames like field1, field 2 etc., There is a XML file with Descriptive text for all the fields. Its like I have to fetch the data from the SQL and use the header/description corresponding to the fields from the XML to report it in the .aspx file.

I have the data imported via the tableadapter. I should be able to read the XML file and extract the field name and description in to an array. Am Not sure whether this is the right way of doing it??? Even if I could extract, not sure about how to associate the header in the array and the data in the dataset. Any ideas will be sincerely appreciated. thanks in advance.

If you have an xml file, or fragment, why do you need to create an array? Use XDocument, or XElement to navigate the document. If you're not using .net 3.5 XDocument will work also.

Hi !! everyone

My problem is that , I am using Grid View Control with pagination.. pagination is working perfectly.. I am using 10 check boxes in each row. Selecting/ deselecting them using java script.. I select particular role from combo box assign it with access(using check boxes) and sending those values to database. After that when i select particular role, i want to show those saved values... But only those much rows get populated which r present in first page of grid view control and which r present on second page not reflected.. please send me some solution if there is....

can you clarify your question as i am not getting that first page data is reflected and other are's not.
please put your code with details explanation.

On Save button click i am saving all selected access into database..

i am using function similar to this

protected void CmdSave_Click(object sender, EventArgs e)
{
string StrRoleAcccess = "";
string StrOption = "";
string StrChkAccess = "";
string StrFlag = "";
if (CBRoleName.SelectedItem.Text != "--Select--")
{
trErrMessage.Visible = false;
for (int RowCnt = 0; RowCnt < GrdAccess.Rows.Count; RowCnt++)
{
foreach (GridViewRow RowFile in GrdAccess.Rows)
{

for (int i = 2; i < RowFile.Cells.Count; i++)
{
//RowFile.Cells[2].Controls[1].ID
if (RowFile.Cells[i].Controls[1].GetType() == typeof(CheckBox))
{
CheckBox ObjCnt = new CheckBox();
ObjCnt = (CheckBox)RowFile.Cells[i].Controls[1];
if (ObjCnt.Checked)
{
StrFlag = "True";
// FrLoadChkCount++;
} } } }

if (StrFlag == "True")
{
foreach (GridViewRow RowFile in GrdAccess.Rows)
{
for (int i = 2; i < RowFile.Cells.Count - 1; i++)
{
//RowFile.Cells[2].Controls[1].ID
if (RowFile.Cells[i].Controls[1].GetType() == typeof(CheckBox))
{
CheckBox ObjCnt = new CheckBox();
ObjCnt = (CheckBox)RowFile.Cells[i].Controls[1];
if (ObjCnt.Checked)
{

{
Label LblFldOption = (Label)RowFile.Cells[i].FindControl("lblAcronym");
StrOption = LblFldOption.Text.ToString().Trim() + "_";
HiddenField HidCnt = (HiddenField)(RowFile.Cells[i].FindControl("Hid" + ObjCnt.ID));
StrChkAccess = HidCnt.Value;
StrRoleAcccess += "," + StrOption + StrChkAccess;
} } }}}
StrRoleAcccess = StrRoleAcccess + ","+Session["ArrayTobeSaved"].ToString();
...... //Saving those value in database
}}}

I am able maintain the status of all check boxes in every page on pagination...
I use RememberOldValues() and RestoreOldValues() function for that..

I am facing the problem when I retrieve all saved status of check boxes from database and show them when user select particular role from Combo box.

The status of selected Check boxes of first page get reflected but the status of check boxes on second page did not get reflected... one can say binding data to second page of grid view is not working.... Cry | :((

here is some part of coding
protected void CBRoleName_SelectedIndexChanged(object sender, EventArgs e)
{
Session["ArrayTobeSaved"] = "";
string[] StrArrOptionAcroName;string[] StrArrOptionName;string StrOptionName;
DataTable DtObjRAccess = CSUserRole.RoleAccesslist(CBRoleName.SelectedItem.Value);
GridView DemoGrid = new GridView();
DemoGrid.DataSource = DtObjRAccess;
int pageCount = GrdAccess.PageCount;
int DemoPageCount=0;

if (DtObjRAccess.Rows.Count > 0)
{
for (int RowCnt = 0; RowCnt < DtObjRAccess.Rows.Count; RowCnt++)
{
StrOptionName = DtObjRAccess.Rows[RowCnt].ItemArray[0].ToString();
if (StrOptionName != "")
{

StrArrOptionAcroName = StrOptionName.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries);
StrArrOptionName = new string[StrArrOptionAcroName.GetLength(0)];
var Optname = new ArrayList();
var AcroName = new ArrayList();
for (int index = 0; index < StrArrOptionAcroName.Length; index++)
{
StrArrOptionName = StrArrOptionAcroName[index].Split('_');
Optname.Add(StrArrOptionName[0]);
AcroName.Add(StrArrOptionName[1]);
}

for (int rowIndex = 0; rowIndex < Optname.Count; rowIndex++)
{ int i=0;
int j=0;
DemoPageCount = 0;
while (DemoPageCount < pageCount)
{
i=0;
j=9;

for(int p=i;p<=j;p++)
{
GridViewRow GrdRow= GrdAccess.Rows[p];
Label LblON = (Label)GrdRow.FindControl("lblAcronym");
if (LblON.Text == Optname[rowIndex].ToString())
{
int rdx = Convert.ToInt32(GrdRow.ID);
switch (AcroName[rowIndex].ToString())
{
case "C":
CheckBox objChk = (CheckBox)GrdRow.FindControl("ChkNew");
if (objChk.Enabled)
{ objChk.Checked = true; }
break;
case "E":
CheckBox objChkE = (CheckBox)GrdRow.FindControl("ChkEdit");
objChkE.Checked = true;
break;
case "D":
CheckBox objChkD = (CheckBox)GrdRow.FindControl("ChkDelete");
objChkD.Checked = true;
break;
}
}

}//end for
DemoPageCount++;
GrdAccess.PageIndex = DemoPageCount;
}//endwhile
}

}

}
}
else

Can u help me in this situation ......

You need to maintain the sate of the Gridview for every page during paging.
Have look into this article,
Maintaining States of Selected CheckBoxes in Different Pages inside the GridView[^]

This will help you Big Grin | :-D

Is it possible to maintain treeview state across postbacks? I have a treeview on a masterpage. I want the treeview to maintain its expand/colapse state when the user navigates to different pages.

If am not sure if you tried to serach this on google, but I found some very interesting links. Give this [^]a try.
And if you still do not find any answer, come back here I'll explain this to you. Smile | :)

Don't you think this would be a good learning excercise? Smile | :)
