Web Forms :: Firing A C# Function ServerSide On A Dynamic HTML Control?

Jul 28, 2010

I am trying to create an HTML button that can use a C# server side delete function. since I don't know how many results I will have at the page, the control is created dynamically when the end user searches for current Messages:

CmsContactUsContent += string.Format(" "<input type='image' value='delete' id='del{8}' runat='server' onClick='DeleteItem' img src='/MaromyDotNet/img/AdminIcons/note.png' style='width:16px;'/>" + [code].....

Run Server Side Function On Dynamic HTML Control?

Jul 28, 2010

I am trying to create an HTML button that can use a C# server side delete function. since I don't know how many results I will have at the page, the control is created dynamically when the end user searches for current Messages:

CmsContactUsContent += string.Format("
"<input type='image' value='delete' id='del{8}' runat='server' onClick='DeleteItem' img src='/MaromyDotNet/img/AdminIcons/note.png' style='width:16px;'/>" +
"</div>" +
"<div style='clear:both'></div></div>", message.ContactMessageId);

There is a Class called ContactMessage and I'd like at each iteraion to allow the user to delete the current message through this function:

public void DeleteItem(object sender, EventArgs e)
{
int idToDelete = 41;
BLLContactMessage.deleteMessageById(idToDelete);
}

However, the event does not fire.

Web Forms :: Dynamic Control Event Not Firing Second Time?

Jan 8, 2010

i am using VWD(visual web developer 2008) and DOTNET 3.5

i have a page on which i dynamically add multiple datalist controls on the oninit event of my page , on postabck i again add all these datalist controls to the page on oninit event

the template for all the datalist controls is defined using the ITemplate interface, the template defined for each datalist control contains a button which has a event handler attached to onclick event.

the problem is first time i click the button on postback i add the multiple datalist controls , the event gets fired which modifies the datatable i am using to generate my datalist controls and the datalist controls with the modified data show on the page but the second time a user clicks the button inside datalist the event does not get fired.

C# - Dynamic Control Click Event Not Firing Properly?

Jun 7, 2010

I'm creating a next/previous function for my repeater using pageddatasource. I added the link button control dynamically in my oninit using the following code.

LinkButton lnkNext = new LinkButton();
lnkNext.Text = "Next";
lnkNext.Click += new EventHandler(NextPage);
if (currentPage != objPagedDataSource.PageCount)

[Code]....

So I am incrementing the cookie I am using to track the page number and then rebinding the repeater.

Here is the main issue. The first time I click Next, it works, it goes to Page 2 without any problems. When on Page 2, I click Next, it goes back to Page 1. Seems like the Next event is not wiring up properly.

Web Forms :: Pass Variable As Html Control Through To Javascript Function

Jan 24, 2011

I have a function that gets the position of a control.

[Code]....

All the function needs is an htmlcontrol being fed to it as the parameter (elemRef). I can declare a variable in Javascript of the same content page but different function and pass the parameter successfullly getting returned values. For example, if I have the following function:

function (getPosition)
{ var txtBox1 = document.getElemendById('<%=txtBox1.ClientID %>');
getPos(txtBox1);
}

I will get the coordinates of the control txtBox1. But how can I accomplish this if I am calling this function from a javascript function or codebehind of the Master Page, or codebehind of the same content Page.

Web Forms :: Dynamic Image Button Not Firing When Id Assigned

Mar 3, 2010

I am having an odd situation with a dynamic image button. This button is part of a dynamically built asp table which lives in a repeater. Not sure if that complicates things or not, but here's the issue. Since the buttons are dynamically built, if I let asp.net handle the ids I get a crash on postback. Not entirely sure why, but If I set the id in code, I don't get the duplicate id error but I don't get the event fired either. Here is the code building the button:

[Code]....

With this code the IB_Validate_Click never fires. If I comment out the IB_Validate.ID line, the event fires. But, as mentioned above, I have an id clash on a postback. Any ideas why the IB_Validate_Click doesn't fire on this button if the id is set?

Web Forms :: Dynamic Checkboxes Not Firing Oncheckchanged Event?

I'm sure the answer to this problem is very simple, however, I've been racking my brain on this one. I am adding rows/cells to a table dynamically.

[Code]....

When I check or uncheck the box, it fires the page load and not 'MarkFormCompleted'. No matter what I do, I can't get it to fire 'MarkFormCompleted'.

Serverside Controls Vs Html Controls From AJAX Point Of View

Mar 8, 2010

i know this question have been mentioned alot here but mine is a little more updated, now with ASP.net 4 and new Ajax client templating plus JASON services. so if i got all these new capabilities will i really need server side controls as long as i can bind on client side, create data-views on client side heck i can even use data-context and apply CRUD operations on clients side.

so i actually i wont need button_click server side event or what so ever... i am asking this because i own some commercial Controls like Telerik and Component art and they both offer client side operations ow but still i am confused as to my knowledge creating these controls will still have to go through Page Life cycle

Forms Data Controls :: Dynamic CheckBox Inside GridView Not Firing Events

Nov 8, 2010

I've been reading up on the problems with dynamically created controls and how they have been solved. The posts I have come across are creating the controls in a panel or some other open place. I can't seem to get my checkbox to fire the event from inside a gridview. below is the code behind from inside the GridView PreRender event.

[Code]....

..And the Checked Event..
[Code]....

So after all this, nothing happens. I get the postback flash but my command inside the checked event doesn't fire.I tried putting the dynamic creation of the checkbox in Page Load with no effect.. I think because I can't place the checkbox inside the GridView under page load.

I have a javascript function named as sss() . I want to call it from the code behind.

function sss() {
$("#div-TableContent").show("slow");
alert("its Works");

If (Not ClientScript.IsStartupScriptRegistered("sss")) Then
Page.ClientScript.RegisterStartupScript(Me.GetType(), "alert", "sss();", True)

C# - Pass Model Values As Javascript Function Parameters From Inside Mvc Html Helper Such A Html.Radio?

Jul 20, 2010

I think I need to drop in some escape characters, but I'm not quite sure where. Here is the javascript function I'm attempting to call:

function setData(associateValue, reviewDateValue) {
var associate = document.getElementById("Associate");
var reviewDate = document.getElementById("ReviewDate");
associate.value = associateValue;
reviewDate.value = reviewDateValue;
}

Here is the asp .net mvc line where I'm attempting to create a Radio button with a click event that calls the above function and passes data from the model as javascript parameter values.

<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('<%=item.Associate%>','<%=item.ReviewDate%>' )" } )%>

The above throws a bunch of compile issues and doesn't work. A call such as the following does call the javascript, but doesn't get the data from the model.

<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('item.Associate','item.ReviewDate' )" } )%>
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('item.Associate','item.ReviewDate' )" } )%>
<% String functionCall = String.Format("setData('{0}','{1}')", Html.Encode(item.Associate), Html.Encode(item.ReviewDate )) ; %>
<%= Html.RadioButton("Selected", item.Selected, new { onClick=functionCall } )%>

VS 2010 Dynamic UserControl - Postback Event Not Firing

Feb 8, 2012

I have a page where I add a dynamic user control in the Page_Load event based on criteria.

The control is a simple form with a save button. The problem is the _Click event never fires for the button. It will postback the main page the control is within, but not the code behind for the control...so I never get the button click even, and therefor can't execute the save code.

Tried it in the init, tried adding the control to a placeholder, tried a lot of various things but nothing seems to work.

Code:
If cb_business_profile.Items.Count = 0 Then
Dim u_pnl_content As UpdatePanel = Page.FindControl("u_pnl_content")
u_pnl_content.ContentTemplateContainer.Controls.Clear()

Dim business_profile_detail As Control = LoadControl("~/controls/business_profile_detail.ascx")
