hello friends,
I am using a button to Generate a dataset and DataBind the dataset to a GridView..
But when paging is enabled to the GridView and when we click on page numbers i have to click the button again to display the data again...
whether i have to write some Code in PageIndexCahnged or Changing???
My Button Click Event is Like This
protected void cmdSearchAll_Click(object sender, EventArgs e)
{
gvCandidates.Visible = true;
// ProcessSelectAllCandidates is a Process From Business Logic Layer Which Will Generate a DataSet When Invoked(in try block) Then the DataSet (ie.ResultSet) is assigned as DataSource to GridView
ProcessSelectAllCandidates allcandidates = new ProcessSelectAllCandidates();
try
{
allcandidates.Invoke();
}
catch
{
Response.Redirect("~/ErrorPage.htm");
}
gvCandidates.DataSource = allcandidates.ResultSet;
gvCandidates.DataBind();
}
what will be the problem??
thanks in advance
regards
your friend

Hi Faz,
For my case, i will write a code in PageChanging.
protected void GridView1_PageChanging(object sender, GridViewPageEventArgs e)
{
GridView gv = (GridView)sender;
gv.PageIndex = e.NewPageIndex;
//Bind the data to the GridView again
}
I have no idea if this is the problem that you have.
Regards,
Henri

Hello All,
I m opening a pop up window from the web page(Asp.net/Vb.net) say (form1),
to open the window,im using,window.open(form2)
im fetching the data from the form2 back to form1,
while doing this,the data that already exists in the form1 is getting erased
,the page is getting refreshed
I can use sessions, but the amount of data that i have to transfer is large.
Can anyone suggest a way to fetch data from the other form,without refreshing the current page
Thanks in advance
Pls look into it,its very urgent
Regards,
Kavitha

Place a hidden field in the parent document...try to access this hidden field in the childwindow through the javascript...(hint:use document.parent.getElementbyId...)..place all the required values into the hidden field probably with a delimiter .Now u can access this hidden field value easily inside the parent window

When u close the Popup window r u refreshing the parent window. if u r doing this then dont refresh ur parent window then that time ur grid will not bind once again and get the values in the session.
Thanks and Regards

hi Aavesh,
Ye,this is what im looking for,im not able to avoid the parent window from refreshing,as im putting the data from form2 into the textbox which is in parent window,parent window is refreshing
i have attached the code,like,how im calling the child window and how im going back to parent window.
let me knw,if i can correct something
calling pop-up window
------------------
"javascript:var w=window.open('Showdetails.aspx?ID=20','','menubar=No,toolbar=No,resizable=yes,scrollbars=yes,status=yes,width=550,height=200,left=150,top=200,screenX=200,screenY=200');"
going back to parent window
----------------------------
Dim script As String = "" + _
" window.opener.location = " + Chr(34) + "FST001_REG-ENQ.aspx?id=20&enquiryno=" + Session("enqno") + Chr(34) + "; " + _
" window.close() " + _
""
ClientScript.RegisterStartupScript(Me.GetType(), "CloseWindows", script)

hi,
why r u using this window.opener.location. and i didn't get why did you passing this querystring when u have id is a static value and the enquiryno is already u have taken in session variable. u will diretly get the value of Session("enqno") in the parent window.
Instead of using this window.opener.location remove this line
and close the window with window.close() only.
Try this.
Thanks and Regards

have you tried is it working or not....
|
|

hi
sorry,it should actually be,
Dim script As String = "" + _
" window.opener.location = " + Chr(34) + "FST001_REG-ENQ.aspx?id=20&enquiryno=" + enqno + Chr(34) + "; " + _
" window.close() " + _
""
ClientScript.RegisterStartupScript(Me.GetType(), "CloseWindows", script)
im using requery string in the parent window and accssing the enqno,so that no memory is allocated
i tried using session,but if i just simply close the child window,the page load event in the parent form is not firing,its not refreshing,at the same time,data is not pushed to the parent form
Any solution?

FORM1<br />
-----------------------------<br />
use html image button<br />
<br />
<br />
<br />
<br />
<script type="text/javascript"><br />
<br />
function Click()<br />
{<br />
window.open("form2.aspx");<br />
}<br />
<br />
</script><br />
<br />
<br />
<br />
call the click function<br />
-----------------------------<br />
<br />
<img src="Images/zoom.jpg" onclick="Click()" style="width: 25px; height: 16px" /><br />
<br />
<br />
form2<br />
--------------------<br />
<script type="text/javascript"><br />
function Click(code)<br />
{ <br />
window.opener.document.form1.txt1.value=code;<br />
<br />
window.close();<br />
}<br />
<br />
<br />
</script><br />
<br />
<br />
<br />
<br />
in form2 <br />
-----------<br />
under gridview_rowdatabound<br />
<br />
If e.Row.RowType = DataControlRowType.DataRow Then<br />
Dim linkbutton As LinkButton = CType(e.Row.FindControl("lblcd"), LinkButton)<br />
Dim code As String = linkbutton.Text<br />
refno = "ENQR" + "/" + code<br />
CType(linkbutton, LinkButton).Attributes.Add("onclick", "JavaScript:Click('" & <br />
<br />
refno & "');")<br />
End If

yes.you can get all the values without refreshing page and also you dont need to get value in session.
follow step
suppose i have two textbox in form1 and one link button to open popup window.
now i am passing these textboxes id to popup window(Form2)
Javascript code
function OpenWindow(id1,id2)
{
ref = "Form2.aspx?id="+id1+"&id2="+id2;
var strFeatures="toolbar=no,status=no,menubar=no,location=no"
strFeatures=strFeatures+",scrollbars=no,resizable=no,addressbar=no,height=250,width=220"
newWin = window.open(ref,"TellObj",strFeatures);
newWin.opener = top;
}
Pass Id1 and Id2 to openWindow function
linkButton.Attributes.Add("onclick","OpenWindow("+txt1.ClientID+","+txt2.ClientID+");");
Onclick of linkButon,popWindow will be open.
Now in form2, i have two textboxes and one button.
now onPageload event,save these two ids in hidden field, called hid1,hid2
onPage Load event
hid1.value=Request.QueryString["Id1"];
hid2.value=Request.QueryString["Id2"];
on click of button call javascript
function setValues()<br />
{<br />
opener.document.getElementById('hid1').value=document.getElementById('TextBox1').value;<br />
opener.document.getElementById('hid2').value=document.getElementById('TextBox2').value; self.close();<br />
}

Are you getting javascript Error?
If no, then please check out javascript function with only alert box.
javascript function is called or not?
you must call javascript on every postback.

Hi,
I am using FIleUpload Control for uploading, But at by clicking upload button I am just displaying image not saving image.
I m using this statement:
imgIcon.Src = FileUpload1.PostedFile.FileName;
This works fine in IE but gives only filename in Mozilla. This statement gives full filepath in IE.
