C# - How To Get Sorting Without Removing Row-Created Function(Use For Changing Column Of Header-text In Run-time)

Nov 15 10 at 4:35

The following code is my Grid View AA from aspx page.

<asp:GridView ID="GridView_AA" runat="server" OnSorting = "Gridview_AA_Sorting" OnRowCreated="GridView_AA_RowCreated">
<asp:TemplateField HeaderText="Period Name" SortExpression="PERIOD_NAME">
[code]...

I cannot sort after adding GridView_AA_RowCreated function. Each column of Grid view header-text worked well before I add this Row Created function. If I cut the following code: e.Row.Cells[2].Text = "Period Name";
Sorting works. I want to get sorting without removing this Row Created function. Do you have any brighter solution about my problem?

protected void GridView_AA_RowCreated(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
e.Row.Cells[2].Text = "Period Name"; //Change header text in run-time
}
}

VS 2008 Changing The Header Text Of An Autogenerated Gridview?

Jul 10th, 2009, 10:11 AM

OK - So I used to be a puerly code generated gidview guy... it gives you much more control - it also creates tons more work! so with this recent project I am working on I used a gridview that gets populated from a SQL data source that is right there in my ASPX page. I love that is just handles the sorting and paging for you.There are a few questions I have though - is is possible to change the header text? ideally I would like to replace it with an image that lets the user know which direction the sort is (ASC or DESC) for a particular column. I would settle for just changing the text from the names of the database columns though Also - I need to add a row that displays an icon based on a flag in the data base accepted rejected or canceled. I was able to add a check box item but how to I make decisions based on data that is returned from the database - where could I do that without breaking the sorting and paging functions?I have looked at several articles about changing the header text but everything I have tried fails - because no matter when i try to access the header it tells me the cell isn't there and throws and an exception.

How to make it such that the rows also turn red if condition is met ? I cannot hardcode in columns since the Gridview is autogenerate colums as data structure keeps changing.

Forms Data Controls :: Changing A GridView's ItemTemplate Label Text Dynamically

May 07, 2010 01:33 PM

I'm trying to change the text of a GridView label in an ItemTemplate and I am having some issues. I searched all over and can't find a solution. This is what I am trying to do...

I have a GridView that has a comment field. Normally when the page is rendered the comment field is truncated using a truncate class that limits field length. The full contents can be displayed in a tooltip when the comment field is hovered over. That part works fine.

I also have an export to Excel class that will take the Gridview and export it to Excel and that part works fine as well...

Now the issue... Because of the truncated field, when I do an export it will export exactly what is in that field, the truncated version of a comment. When the export button is clicked I need to change the .text value of the label that is in the GridView ItemTemplate

From this truncated version...

[Code]....

And then back again after the export routine is complete.

I have accessed the contents of a label before using FindControl but never set a value, is this possible? Also, I have captured what is in the comment field on RowDataBound but by that time, it is already truncated.

Dynamically Changing Text Box Value Not Working?

Dec 24, 2008 04:45 PM

I have a text box (txtMessage) and in the Page load event I am assigning a value to it.

<asp:TextBox
ID="txtMessage"
runat="server"
Width="300"></asp:TextBox>
protected
void Page_Load(Object sender,
EventArgs e)
{
txtMessage.Text = "Welcome to my page " + Member.UserName;
}

So when the page loads the form displays this message in the text box. But the user can change this message. So if a user change this message and click a submit button the message never gets changed to what ever the user typed. It still says "Welcome to my page....". I was able to see this because when a user clicks on submit button, I get this as an email. So how do I change it? I tried is post back on the button onclick event but not working

protected
void btnSend_Click(object sender,
EventArgs e)
{
string strSubject =
"";if (this.IsPostBack)
{
strSubject = txtMessage.Text.ToString();
}

//then rest of the code goes here to send this as a email message

On my website I am putting some short stories in and allowing people to change the name of the characters in the story to match their own. I was going to keep the stories in a SQL DB but not quite sure how I would go about changing the names of the characters dynamically?

Would I be best using say (Name1), (Name2) etc in the stories in the DB then changing it using a string query on the code behind or is there a better / quicker way to acheive this?

Forms Data Controls :: Dynamically Binding Dataset Table Values To Datagrid's Header Column?

Jun 29, 2010 10:26 AM

I want to dynamically bind dataset values into datagrid's header datafield.

Is it possible? To be more clear, when you click on datagrid's (Collection) from properties window, you get selected columns created from Bound column. So in those columns I want to dynamically display dataset's table values in those columns.

i.e like ds.Tables[0].Rows[0][0].

Is it possible to do it in Datagrid ItemDataBound function like,

e.Item.Cells[1].Text = ds.Tables[0].Rows[0][0]

or something like this? I know the above code is wrong and wont work since I tried it out and while building it throwed error saying, Cannot implicitly convert type 'object' to 'string'.

VS 2005 Gridview Header Column Be Hyperlink?

Aug 6th, 2009, 02:22 PM

Usually when you click the header of a gridview column it means you want to sort on that column. Can I instead have it be a hyperlink to another page? The reason I am asking is because I am converting an ASP page, and that is how it works there. Obiously it's not a gridview though. I was thinking of an alternative that's a button outside the gridview. The gridview shows statuses, such as Pending 3, and there is a status legend that explains what the statuses are. It is this legend I want to display when a user clicks the header. I suppose another alternative would be to put it in each cell, i.e. Pending, Closed, Active could all bring up the legend.

Forms Data Controls :: GridView Disappears When Click A Column Header To Sort?

Jul 28, 2010 06:06 PM

I have a page with a TextBox, a Button, a GridView, and a SqlDataSource. I click the Button to execute the SQL in the TextBox using the SqlDataSource. The SqlDataSource populates the GridView. Everything works as expected until I click a column heading to sort.

When I click a column heading, the GridView disappears and I have to click the Button to display the grid again. When I do, the grid is displayed in the order of the column I clicked.

I don't understand why the GridView is disappearing when I click a column header.

Does anyone know how to fix this so the GridView is sorted and displayed only by clicking the column header?

Forms Data Controls :: Div Collapses Every Time Click On GridView's Sort Column Header?

Feb 08, 2010 02:28 AM

I have several grid views indide div's, and when I click the Sort header on an open div the div collapses and no sort happens. I believe it is just reloading the entire page but when I surround PageLoad with !ISPostBack then the page redraws as blank. Since the sort script is generated by the GV, I don't know how to stop it from creating side effects.

Here's my code:

<script type="text/javascript" language="javascript">
function toggleDisplay(id) {
var obj = document.getElementById(id);
obj.style.display = (obj.style.display == "none") ? "" : "none";
return false; // cancel the href
}
</script>
