No. The format parameter is the same string you'd pass to String.Format[^], with a single placeholder representing the value returned from the data source.
Eval("rblPurchaseType","rblPurchaseType") will literally return the string "rblPurchaseType", since there is no placeholder in the format parameter.
If you wanted to return the value of the field as a string, you'd need: Eval("rblPurchaseType", "{0}")
But since the AddWithValue method takes an object, you'd be better off using the overload that doesn't convert the value to a string:
cmd2.Parameters.AddWithValue("@ptype", Eval("rblPurchaseType"));

Ahhhh!
I will try with the "{0}"
I had tried the second option before posting here the first time and it did not work.
This:
d2.Parameters.AddWithValue("@ptype", Eval("rblPurchaseType"));
Maybe I did something wrong.
Thanks very much.
UPDATE: Tried both options but still end up with following error message:
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.

If you're doing this from the code-behind, you'll need to be in a DataBinding event handler for your data-bound control. Otherwise, ASP.NET has no idea where you want to get the data from.

how can I use rich textbox in web application without using third part

It entirely depends on what you want to build, what framework you are using and how much do you know about a Rich Text Box. Since, you have asked this under ASP.NET, I can tell you that HTML can be used to build a basic RichTextBox here,
<div contenteditable="true">
Some content here, it can be edited with the support of CTRL B and CTRL I modifiers.
</div> You can try that code in any online fiddle, and see that the element would allow users to modify the content, through the use of CTRL + B and CTRL + I etc. Secondly, in ASP.NET there are some built-in text boxes, but they are not rich one, thus you would require to use a third-party, Rich Text box in asp.net | The ASP.NET Forums. It depends on how much effort you want to put into this project of yours. 
As I mentioned, if you want to build a complex text editor, consider using one of the famous text editors out there instead of building your own text editor — rich text editors, and text editors online are quite similar, Google WYSIWYG for instance; TinyMCE | The Most Advanced WYSIWYG HTML Editor.

Hello again.
This is the last installment of my project.
was using Gridview1_RowDeleting with similar code below to delete a dynamically generated row.
That worked great.
Now, I am trying to use the code below to accomplish similar function only this time, with Repeater control.
I can't get past int rowID = e.RowIndex.
Any ideas how to work around this?
Markup:
<asp:Button ID="btnDelete" runat="server" Width="70"
Text="Remove" CommandName="Remove"
CommandArgument='<%# Container.ItemIndex %>' />
I have also tried this:
sp:Button ID="btnDelete" Style="width: 120px;" runat="server" Text="Remove a row"
OnClick="btnDelete_Click" CssClass="btnclass" />
C#
otected void btnDelete_Click(object sender, EventArgs e)
{
int rowIndex = 0;
int rowID = e.RowIndex;
lblTotal.Text = "0";
if (ViewState["CurrTable"] != null)
{
DataTable dtCurrentTable = (DataTable)ViewState["CurrTable"];
if (dtCurrentTable.Rows.Count > 0)
{
for (int i = 1; i <= Repeater1.Items.Count; i++)
{
TextBox tbboatregNum = (TextBox)Repeater1.Items[rowIndex].FindControl("txtboatregNum");
TextBox tbPayerret = (TextBox)Repeater1.Items[rowIndex].FindControl("txtPayerret");
TextBox tbCGvesselNum = (TextBox)Repeater1.Items[rowIndex].FindControl("cgaurdNumber");
TextBox tbCGtaxpayerret = (TextBox)Repeater1.Items[rowIndex].FindControl("cguardreturnedval");
dtCurrentTable.Rows[i - 1]["boatregNum"] = tbboatregNum.Text;
dtCurrentTable.Rows[i - 1]["taxpayerret"] = tbPayerret.Text;
dtCurrentTable.Rows[i - 1]["CGvesselNum"] = tbCGvesselNum.Text;
dtCurrentTable.Rows[i - 1]["CGtaxpayerret"] = tbCGtaxpayerret.Text;
rowIndex++;
}
if (e.RowIndex < dtCurrentTable.Rows.Count)
{
dtCurrentTable.Rows.Remove(dtCurrentTable.Rows[rowID]);
}
}
ViewState["CurrTable"] = dtCurrentTable;
Repeater1.DataSource = dtCurrentTable;
Repeater1.DataBind();
}
SetPreviousData();
}
Many thanks in advance

Where have you seen that EventArgs has an RowIndex property?
The moment you moved from Grid to Repeater you lost all the help. Repeater does not maintain a table-like structure, every block created from the template stands on its own...
That's the reason you have to pass identifying parameters to the template, like CommandArgument='<%# Container.ItemIndex %>'... Use that to find the row to remove!

Alex: Fix it? How you gonna fix this?
Skipper: Grit, spit and a whole lotta duct tape.

Kornfield,
Thanks for your response.
Just so I understand your point, you are saying that if I use the following:
sp:Button ID="btnDelete" runat="server" Width="70"
Text="Remove" CommandName="Remove"
CommandArgument='<%# Container.ItemIndex %>' /> ,
then I would be able to use the C# with rowIndex as is?
|
|
|
|
|
No!!!
What I'm saying, that you have no way to use a property that does not exist on the object, but you can fill in the gap by passing the value on the CommandArgument property of the button initiated the event...
So instead of e.RowIndex you can use btnDelete.CommandArgument...

Hi
I ran the fortify scan to see if we have any vulnerabilities and found some of them wrt cross site scripting poor validation on the .aspx pages. Tried the below following methods to solve but still Fortify shows as vulnerability.
Here's my code.
<asp:label id="lblCsf" runat="server" text="<%# AntiXss.AntiXssEncoder.HtmlEncode(Eval("Max").ToString, True) %>">
<asp:label id="lblCsf" runat="server" text="<%# HttpUtility.HtmlEncode(Eval("Max")) %>">
Appreciate if any of you can suggest some solution for this scenario.

Thanks for your response, but initially it was : and since fortify was showing as cross site vulnerability so I have changed to use AntiXss. But still it shows the same vulnerability. The only difference was while using : , it says Cross site vulnerability and when using AntiXss, it says Poor cross site vulnerability.

Still sounds like a bug in Fortify to me.

Hi,
I am creating a ASP.Net, Web Api web application which I am planning to use mostly the Web Api for the Business and Data Access calls, trying to avoid the MVC Controllers, as I am mostly using Web Api calls and Web Api doesn't support Sessions, what I am trying to do is to keep/pass Session values as hidden fields in html pages. And in every call those values will be passed to the Web Api methods and back to the UI to be stored in the Hidden fields.
My question is, is this a good approach or very bad approach, if its bad approach can you please guide me what are the alternative good approaches. I am not familiar much with the ASP.Net MVC, I was very good in WebFarms sometime back, trying my best to come out of that old thinking bros, need some help.
Thanks in advance.
Thanks,
Abdul Aleem

Hi Friends,
we are facing issue in website goes down in frequently, starting to working on after recycling app pool.
Configuration and technology:

The application code running that particular site is throwing an un-handled exception and is locking up the process until it is reset (recycled). Check the event viewer, you will likely find some .NET errors lodged in there.

Hi,
I am trying to create modal dialog which contains Text-boxes and drop-downs which are going to get the Data from the parent page, but its not creating the modal dialog but its putting the values on the same parent page. Here is how I have created the modal
$('#btnViewJob').click(function (event) {
var mytext = 'My first modal dialog using MVC: <input type="text" value="Some value comes from parent page" id="temp"' + somevaluecomesfromparentpage + '" />';
$('<div id="dialog"><table><tr><td>' + mytext + '</td></tr></table></div>').appendTo('body');
event.preventDefault();
$('#dialog').dialog({
autoOpen: false,
width: 400,
resizable: false,
title: "hi there",
modal: true,
buttons: {
"Close": function () {
$(this).dialog("close");
}
}
});
});
Thanks,
Abdul Aleem

You've specified autoOpen:false, so the first time you click the button, the dialog is created but never shown.
The next time you click the button, you create a new <div> with the same ID, and append it to the body. IDs are supposed to be unique, so the #dialog selector only returns the first element with that ID. Since the dialog(...) call is what hides the element, the subsequent elements are never hidden, and appear at the end of the body.
You need to change the code so that it uses the existing element on subsequent clicks:
$('#btnViewJob').click(function(event) {
event.preventDefault();
var mytext = 'My first modal dialog using MVC: <input type="text" value="Some value comes from parent page" id="temp"' + somevaluecomesfromparentpage + '" />';
var dialog = $("#dialog");
if (!dialog.length) {
dialog = $("<div/>").attr("id", "dialog").appendTo("body");
dialog.dialog({
autoOpen: false,
width: 400,
resizable: false,
title: "hi there",
modal: true,
buttons: {
"Close": function() {
$(this).dialog("close");
}
}
});
}
dialog.empty().html("<table><tr><td>" + mytext + "</td></tr></table>");
dialog.dialog("open");
});
