I'm sending you the code.In this, when we refresh the page, "gvQA.Rows.Count" shows 0 rows.
Here's code:
protected void Page_Load(object sender, EventArgs e)
{
if (Page.IsPostBack == false)
{
gvQA.DataSource = null;
gvQA.DataBind();
BindQues();
}
}
#region Methods
public void BindQues()
{
try
{
if (Session["BindData"] == null)
{
ds = new DataSet();
ds = objGet.GetData(Request["JT"].ToString());
litMsg.Text = "Online Test";
if (ds != null)
{
if (ds.Tables[0].Rows.Count > 0)
{
gvQA.Visible = true;
gvQA.DataSource = ds;
gvQA.DataBind();
Session["BindData"] = ds;
}
else
{
gvQA.Visible = false;
}
}
}
else
{
ds =(DataSet)Session["BindData"];
gvQA.Visible = true;
gvQA.DataSource = ds;
gvQA.DataBind();
}
}
catch (Exception ex)
{
Response.Write(ex.Message);
}
}

1- Exception Handling Block
You can user the Error handling application block provided by Microsoft.
Exception Block[^]
2- ELMAH
In some of my previous projects I have used ELMAH ELMAH[^]
ELMAH is very efficient in exception handling with simple configuration.

Dear All,
I am looking to add SplitButton Control in my webpage but I dont know what its called in ASP.Net
you can see that in following link http://dadafghanistan.gov.af/rc?sessionid=1269861720874211[^]
you just need to login which doesnt requires username and password and you can add columns to build a report, as you add a column an split button is added which you can do other action on that too.
any ideas what control is that?

This is how im creating dynamic textboxes in repeater...
But how do i store viewstate of those textboxs on btnclick event...
so that values of text boxs may not dissappear on post back....

Where you are creating dynamic textboxes in this code?
Or you defined static html inside Repeater?
|
|
|
|
|
<asp:Repeater ID="Rptdescription" OnItemCommand="Rptdescription_ItemCommand" runat="server">
<HeaderTemplate>
</HeaderTemplate>
<ItemTemplate>
<tr style="width:100%">
<td colspan=16>
Description Name/Type & Source <asp:TextBox CssClass="input" ID="TextName" Width="240px" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "DescriptionName") %>'></asp:TextBox>
<!-- <asp:Label ID="TxtName" runat="server" Visible="false" Text='<%# DataBinder.Eval(Container.DataItem, "DescriptionName") %>'></asp:Label>
--></td> <td colspan=8>
<!--<asp:Label ID="TxtDate" runat="server" Visible="false" Text='<%# DataBinder.Eval(Container.DataItem, "Date") %>'></asp:Label>
-->Date <asp:TextBox ID="TextDate" runat="server" Text='<%# string.Format("{0:dd/MM/yyyy}",Eval("Date")) %>'></asp:TextBox>
<cc1:CalendarExtender Format="dd/MM/yyyy" ID="CalendarExtender1" runat="server" TargetControlID="TextDate" PopupButtonID="ImageButton1" >

<br /> <asp:RegularExpressionValidator ID="RegularExpressionValidator14" runat="server" ValidationExpression="(0[1-9]|[12][0-9]|3[01])[- /.](0[1-9]|1[012])[- /.](19|20)\d\d" Display="Dynamic" ControlToValidate="TextDate" ErrorMessage="Please Enter in dd/mm/yyyy format"></asp:RegularExpressionValidator>
</td>
</tr>
<tr style="width:100%">
<td colspan=20 >
<!-- <asp:Label ID="TxtDescription" Visible="false" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "Description") %>'></asp:Label>
--> <asp:TextBox CssClass="input" ID="TextDescript" TextMode="MultiLine" Columns="70" Rows="5" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "Description") %>'></asp:TextBox>
</td>
<td><asp:LinkButton ID="delete" CommandName="Delete" CommandArgument='<%# DataBinder.Eval(Container.DataItem, "id") %>' ValidationGroup="false" runat="server">delete</asp:LinkButton></td>
</tr>
</ItemTemplate>

Okay.Then before creating new row and binding it to repeater, you need to save the edited data in text boxes to some persisting object.
|
|
|
|
|
iam using asp.net with c#.and sql server
table fields are
customername nvarchar
monitors decimal
printers decimal
scanners decimal
some times customers will take only printers , so at that time the textboxes is empty so while saving and updating it is giving errors
Input string was not in a correct format
please give example which helps me.

Why don't you trap for that. if your table field does not allow nulls then you cant insert a null.what you can do is to trap for that and have the reserved word that you will use if the textbox is empty.

Hi,
What kind og error it is giving can you give details here..
Thanks ,

You should set a default value of 0 (zero) for the monitors, scanners and printers fields such that when you go to pass the data to the database all of the items have a valid value (zero should be a valid count for items denoting that whilst they may have 1 scanner, they have no printers or monitors).

Which line of code is causing the error?Can u paste that line of code here?
|
|
|
|

printer.computer,scanner lines are giving error
|
|
|
|
|
try this
in your table set default value of printer, scanner.. parameter is 0
or use in code
if(txt_printer=="")
{
printer =0;
}
else
{
printer =txt_printer.Text;
}
same for scanner . & .........
|
|
|
|

If you are going to do it like that, do it this way:
int printer = (string.IsNullOrEmpty(txtPrinter.Text) ? 0 : Convert.ToInt32(txtPrinter.Text);
Apply the appropriate conversion to txtPrinter.Text.

Dear All,
i have following code
function displayControlName(src,pText)
{
var msg2Display = document.getElementById('spMsg');
msg2Display.innerHTML += '<input type = "button" value="'+src+'" onclick="return displayMsg(src,pText)"/><br>';
return false;
}
function displayMsg(src,pText)
{
alert(src + ' you are here');
return false;
}
I am looking to pass "src" and "pText" javascript variable to a function called "displayMsg", but I have tried different ways to pass the variables from first method "displayControlName" as i have tried
displayMsg(src,pText), displayMsg('+src+','+pText+') and a little more but none worked for me.
any ideas how to pass the variable name src and pText to the javascript function displayMsg from method displayControlName and I am trying to pass it in this statement onclick = "return displayMsg(src,pText)"?

this will be the correct way
displayMsg(src,pText);
and i see you have done it but the question is that these parameters have you declared them anywhere ? show u the part you tried to execute and show us where you declare the parameters to pass to the function.

those variables are as the function args and I am sending only text value to these args
as you see
the function requires two args
function displayControlName(src,pText) and I am only printing that two variables passed to function.
here I am passing var to that function
menuLink.Attributes["onclick"] = "return displayControlName('" + item.Text + "','" + item.Parent.Text + "');";
both item.Text and item.Parent.Text are there but the
onclick="return displayMsg(src,pText);" doesent work.

Look at Prakash , that is exactly what you need to do. your variables are not recognized, they are treated as string.
