Forms Data Controls :: Replace Function In A Gridview?

Jul 26, 2010

I am trying to replace carriage returns from a column in a database (MS access) with the br tag.

This could be easily done in classic ASP with <% = replace(recordsetField , Chr(13),"<br>") %>

Not sure how I would do it with .net (c#)

Forms Data Controls :: Failed To Load Viewstate When Gridview Control - Replace Gridview With Datagrid

Apr 5, 2010

Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.

The above error occurs with gridview control , when used with template field columns with item template / and edit templates etc.
updating a row within gridview, at the time of loadiong it loads perfectly fined, but when tried to modify an existing row within gridview control, then it produces the error. Make sure the grid view control has to be a child control which manages the child table info with in a master form. to reproduce the above problem the grid view must be loading the child records info of a master within the masterform, meaning both master data and gridview data all to be managed in one single form.

I had to replace gridview control with datagrid and then it worked perfectly fine. I wasted almost 4 days of my time., there is no way we could figure out the problem. here is the full info of the problem.

Forms Data Controls :: CheckBox In GridView - Replace With Images?

Jun 15, 2010

I am relatively new to asp.net and program using VB. I have written the following code to try and replace ReadOnly CheckBoxes with an image as the CheckBoxes appear grayed out and difficult to see. The GridView is linked to a SQL DataSource to display information only.

The problem I am having is displaying the image for unchecked boxes where the data (PET) in the SQL table is set to 'false'. The code displays the checkbox image fine when the bit is set to 'true', but no image appears in the GridView rows where the bit is 'false'.

How To Replace A Function Name Using JavaScript And Have It Be Recognized As A Function

Aug 25, 2010

I am trying to replace the JavaScript onclick event handler in ASP.NET that is added to a button control when using validation controls. This is what is output into the HTML from ASP.NET in this scenario:

<input type="image" name="ibSubmit1" id="ibSubmit1" src="button-green-submit.gif" onclick="showProgress1();WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ibSubmit1", "", true, "Group1", "", false, false))" style="border-width:0px;" />

I have looked pretty estensively, and unfortunately there doesn't seem to be a way to modify the function server side before it is injected into the page.

Since I am developing a control and desire it to be non-invasive and self contained, and I am interested in obtaining the validationGroup parameter of the WebForm_PostBackOptions object, it seems that the easiest solution would be to use JavaScript to replace the WebForm_DoPostBackWithOptions function name with my custom wrapper function and leave all of the rest of the parameter information intact - then I can extract the information I am interested in, call my custom functions, and then forward the call on to WebForm_DoPostBackWithOptions.

NOTE: I am using jQuery to build my custom function, so if there is an easier way to do this with jQuery it is an option I will consider.

Here is the code I tried to replace the onclick event handler (not working):

$('[onclick*=WebForm_DoPostBackWithOptions]').each(function() {
var txt = this.onclick;
txt = txt + '';
txt = txt.replace('WebForm_DoPostBackWithOptions','ml_DoPostBackWithOptions');
this.onclick = eval(txt);
});

Using alert(), I verified that the text is being changed correctly, however whether or not I use the eval() function, the onclick handler doesn't seem to recognize it as JavaScript.

I thought of using a regular expression to get the validationGroup value, but this seems like it will be far more elegant and flexible if I can get it working...

Note: If there is a way for my control to interrogate the page it is on to find all of the buttons that will post back (regardless of what type of buttons they are) so I can retrieve the property server-side, this is also something I will consider.

Using RegEx Replace Function In C# ASP?

Feb 18, 2010

How do I solve the problem below? I'm creating a simple content management system, where there is a HTML template with specific markup that denotes where content should be:

<html><head></head><body><!-- #Editable "Body1" --><p>etc etc</p><!-- #Editable "Extra" --></body></html>

Separate from this, there is content in a database field that looks a little like this:

<!-- #BeginEditable "Body1" -->This is Test Text<!-- #EndEditable --><!-- #BeginEditable "Extra" -->This is more test text<!-- #EndEditable -->

As you can guess I need to merge the two, that is, replacing

<!-- #Editable "Body1" -->

with: This is Test Text. I've begun the code here. But I'm having problems using the Regex Replace function that should be located at the very bottom of that For/Each.

//Html Template
string html = "<html><head></head><body><!-- #Editable "Body1" --><p>etc etc</p><!-- #Editable "Extra" --></body></html>";
//Regions that need to be put in the Html Template
string regions = "<!-- #BeginEditable "Body1" -->This is Test Text<!-- #EndEditable --><!-- #BeginEditable "Extra" -->This is more test #EndEditable -->";
//Create a Regex to only extract what's between the 'Body' tag
Regex oRegex = new Regex("<body.*?>(.*?)</body>", RegexOptions.Multiline);
//Get only the 'Body' of the html template
string body = oRegex.Match(html).Groups[1].Value.ToString();
// Regex to find sections inside the 'Body' that need replacing with what's in the string 'regions'
Regex oRegex1 = new Regex("<!-- #Editable "(.*?)"[^>]*>",RegexOptions.Multiline);
MatchCollection matches = oRegex1.Matches(body);
// Locate section titles i.e. Body1, Extra
foreach (Match match in matches)
{
string title = oRegex1.Match(match.ToString()).Groups[1].ToString();
Regex oRegex2 = new Regex("<!-- #BeginEditable "" + title + ""[^>]*>(.*?)<!-- #EndEditable [^>]*>", RegexOptions.Multiline);
//
//
// Replace the 'Body' sections with whats in the 'regions' string cross referencing the titles i.e. Body1, Extra
//
//
//
}

Forms Data Controls :: Simulate The Gridview Function Of Updating Row Or Cell Data

Feb 13, 2010

I have an asp.net page with a gridview control on it but I want to allow the user to also be able to update the selected row from a series of textboxes. I simply need the code for a button click event to do this.

button is called button1
textbox is called textbox1
gridview control is named gridview1
record to be modified is in 3rd column called PlayerName

The row to be edited will always be the only record shown and will always be selected by code I've already written. I will also need to know if the record must be set to edit mode to make the button click code work.
