Give Same ValidationGroup name to all the texbox Control, ValidationControl and the Submit Button Control. It should Work.

Hi Abhijit,
I tried by giving the same validation group name to all the textboxes, validation controls and the button control. But, still the form is submitting blank.
|
|
|
|
|
I did the same, and was working fine. By the way I removed the Regx For Telephone number an then tried.

Add the following to your web.config file
</system.web>
<system.webServer>
<validation validateIntegratedModeConfiguration="false"/>
<modules>
<add name="ScriptModule" preCondition="integratedMode" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>

Hi Zafar,
"which version u r using 2005 or 2008"
I am using .Net (version 3.5) with Sql Server 2005 on my local machine. And on the web server we have .net (v 2.0) with sql server 2005.

you are using framework 3.5 on local while on server you are using 2.0
use the same on both.
Validation don't depend on code behind.
check the property CausesValidation="true" on submit or save button and also check the ValidationGroup
is the same for all controls you want to validate (if u r using Val Group)
i think it will solve your problem

i 've checked the code, causesvalidation property was true.
I am posting the inline code here:

the code is working.. properly.
there is no issue in your code.
but the in the BtnReset set the CausesValidation="false" and in BtnSubmit set the CausesValidation="true"
because no need of validation on Reset button.
Use Same .net framework version on server and your development environment.
(as you said that it is working on local) so its the issue on server.

i want to maintain the checkbox selection state for paging.
i mean to say that if i select two checkbox on gridview and then i go to next page and there i again select one checkbox then i return on first page then what ever the checkbox i have selected from first page should be checked.i am using following.
protected void pageindex_changing(object sender, GridViewPageEventArgs e)

GridView1.PageIndex = e.NewPageIndex;
RememberOldValues(GridView1, "chk2");
refresh();
}
private void RememberOldValues(GridView gridview, string checkboxname)
{
ArrayList categoryIDList = new ArrayList();
int index = -1;
foreach (GridViewRow row in gridview.Rows)
{
index =Convert.ToInt32 (gridview.DataKeys[row.RowIndex].Value);
bool result = ((CheckBox)row.FindControl("chk2")).Checked;
// Check in the Session
if (Session["CHECKED_ITEMS"] != null)
categoryIDList = (ArrayList)Session["CHECKED_ITEMS"];
if (result)
{
if (!categoryIDList.Contains(index))
categoryIDList.Add(index);
}
else
categoryIDList.Remove(index);
}
if (categoryIDList != null && categoryIDList.Count > 0)
Session["CHECKED_ITEMS"] = categoryIDList;
WebMsgBox.Show(Session["CHECKED_ITEMS"].ToString());
}
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)

RePopulateValues(GridView1 , "chk2");
}

{
ArrayList categoryIDList = (ArrayList)Session["CHECKED_ITEMS"];
if (categoryIDList != null && categoryIDList.Count > 0)
{
foreach (GridViewRow row in gridview.Rows)
{
int index = Convert.ToInt32 (gridview.DataKeys[row.RowIndex].Value);
if (categoryIDList.Contains(index))
{
CheckBox checkbox = (CheckBox)row.FindControl("chk2");
checkbox.Checked = true;
// row.BackColor = Color.FromName("#FFAA63");

Hello everyone,
I have placed a User Control inside a modal popup & it is working fine. There is also one Cancel button on the user control which is meant for closing the popup. Since ,it is inside the user control ,I am not getting how to make it the CancelControlId for the modal popup. Do anybody have any idea,how can I achieve this?
|
|
|
|
|
What your cancel button does? It just closing the modal or done any othe operation ?
|
|
|
|
|
Thanx for replying,
The cancel button is not doing anything,it simply needs to close the popup and that too without going to server side. It could be done by setting,that button's id as cancelButtonId of modal popup.But since the button is not on the same page.It's rather inside the user control on that panel, I am not able to use this utility as well.
Please reply.
