I'm trying to implement a custom GridView to find a cell by its name. Here is my class:
[Code]....
how I can implement the SET part of property?
Scenario:
I have a Gridview where I want to handle the Sorting in a custom control that I've added to the header.
I've added this control to my GridView's Header via OnRowCreate event handling. I want the Sort Expressions to persist session to session (via Webparts Personalization)
Here is what I have for adding the custom header control to the GridView Header
[Code]....
This works out well for adding the control, but I can't get anything to persist because these controls are creating initially via postback (per the event) and re-created on all subsequent postbacks. I can't add an If(!IsPostback) because the controls are initially created on the gridview's postback (well at least thats how it's acting when I put it in there) If I were to add this control via the ASP page, not via the Codebehind, I would be able to persist the control. If I try to treat it as though everything is setup correctly, and assign my custom control's controls to [Personalizable], I get a runtime error telling me that I can only have webpartzones in or before Page_init (I'm guessing this is due to when/where the
gridview hits the OnRowCreate event). If there is some fundimental logic I'm missing, or best practices that I'm moving away from,
I have a gridview with 4 columns....time,Collage,Personal and reminder
in first column + is a image Button and 8am is a linkbutton 8am,9am,10am.....etc
are coming from gridview binding with daytime.xml...
time || Collage || Personal || Reminder
8am+
9am+
10am+
11am+
12am+
------
8pm+
Problem (1)
i want to store the value(eg. 8am,9am,10am...) in a string variable on clicking of that cell...
and according to selected time i want to save the event.....
Problem (2)
I want to show data from table named PlannerMaster in the Collage,Personal,Reminder Column..
is it possible to show data in First Column From Any xml file And another 3 Columns from any other table/Datasource.........
Problem (3)
I also want to change the backcolor of column ..according to the saved event
For Example if any event for Personal Category (in our gridview Column no. 3) from 8am to 11am..at that condition i want to show the row 8am to 11 am with backcolor Yellow...
same for Functionality For Collage and Reminder Column .....
this will help user to visualize in which time duration he is engegged/busy.....
I have started to solve these tasks by my own...but want to do this in easy and proper manner..
I have the following function that translates the header row in a gridview:
[Code]....
When I added sorting to the gridview cell.Text does not work anymore. How can I access the header text in the cell?
I have a datarepeater inside which I load a gridview. After the grid's binding is done I create an extra header line to group the columns (that's the only way I could do it, I couldn't figure a way to add an event for a control inside the repeater).That works fine and the page displays perfectly.However everytime I do a postback from other controls, I lose the 2nd header and 1 extra empty line appears at the top of the gridview
View 5 RepliesI am implementing a Datagrid with custom scroll bar(tiny scroller using Javascript).
Here the problem is the Header also scrolls.So how can I make it fixed.
I have one solution like following.
function s()
{
var t = document.getElementById("");
var t2 = t.cloneNode(true)
for(i = t2.rows.length -1;i > 0;i--)
t2.deleteRow(i)
t.deleteRow(0)
Headerdiv.appendChild(t2)
}
Here the header is Fixed(almost problem solved).But the Header columns are not in Correct position corresponding to data columns.
I have a grid view populated with some data included bit fields and I made an export to excel function For each row i need to check the cell with the bit value to change the cell color, but the cell is always empty, even if is the field is set to False or True. foreach (GridViewRow row in gv.Rows)
View 2 RepliesI'm having a weird problem where the GridView cell that I'm programmatically updating turns grey, and throws a null error when attempting to save row. I have been searching all day and have not been able to find a solution. I'm guessing there is a problem with my code, so here it is:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
I am going to use this article but I don't know how to add the Search which is the dropdownlist and textbox
The data in dropdownlist is ContactName and CompanyName

I'm building an n-tier application, with the web client and the class library separate. I'm also using the factory pattern of development, using interfaces to act as containers for different objects they are associated with. The problem I'm expreriencing is that I declared a public interface class in the class library and I can create an instance of it in in my aspx pages but whenever I declare it in my custom control code-side, i get an error, like so:
Error 20 The type or namespace name 'IContentMaker' could not be found (are you missing a using directive or an assembly reference?)
notge that I have inherited the class library namespace using the 'using' keyword just in case you are wondering. My code is like so:
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using TQO_Classes ; //importing the class library project
public partial class PageContentMgr : System.Web.UI.UserControl
{
private IContentMaker _data; //this line throws the error, it works fine on aspx pages
I've a gridview in my web form and I'm using a the following code in my web form's Save button:
foreach (GridViewRow row in gvList.Rows)
if (row.RowType == DataControlRowType.DataRow)
{ for (int i = 0; i < row.Cells.Count; i++)
{
string headerRowText = ???;
How can I get the current cell's header text.
I have a gridview that I want to implemenet a custom pager template using the data pager. How would I go about implementing the IPageableItemContainer, where would I put the code, in a sperate class, in the page class that I am implementing the gridview in and how to implement the code on a gridview.
View 1 RepliesIt happened to add an extra Gridveiw Header in row_databound event , It did worked fine on !Postback but disappered on Page.Postback . Quick google search guided me to move the event to Row_Created event and every thing is okay .
Can any expert post some pointers , differnces between grid row_created vs row_databount with some sample table data created dynamically behaviour of both the events in !Postback and page.Postback .
I am trying to create a composite control - A textbox, gridview and a button. When I create the grid dynamically, I use my function GridViewDataBind() that will basically create the gridview at runtime and bind it with data. In this method, I add a blank column (first column for expand/collapse image), databound columns (using custom Itemtemplate), a placeholder, then a new html row/cell and a child gridview. I want to know how can I add these html rows/cols to my gridview. Here is the code:

Not sure if the approach is right and if I was able to explain my problem?
I am trying to display to gridview some data from the database and add a checkbox column to the grid so that user can check it off.
From the database, I have fields: ClientID, ClientName, ClientEmails.
I want to display those fields to the gridview plus the extra column on the right for "checkboxes" so the gridview should show header like this:
Client Id | Client Name | Client Emails | Check |
The data it will display over a page and I need it scrollable too.
How can I do that?
I have created a custom gridview that show "Select All | Clear All" hyper links in header to select the checkboxes in the gridview. That means that I have added these two hyperlink controls to the gridview header and am not showing the actual column headers.
[Code]....
Now, I want to remove the border that is displayed on the header row. How can I remove it? I tried th.BorderStyle = BorderStyle.None; but it didn't work. I need gridlines in the data rows but the header row should not have any border.

View 1 Replies i have a gridview bound to sql datasource with template fields binding the columns. I have set the Header Style to a css class. I have 3 columns not bound to data as Add, Edit and Delete. When I set the text color to white for the header only the non bound columns go white. The bound columns are BLUE like hyperlink. Any one know a way round this. (If I set the style in the gridview the all columns are white. Want to set in external css file).

I have extended a gridview to add an additional header with following two hyperlink controls "Select All" and "Clear All". These will operate on checkboxes in the data rows of the grid. I hide the column headers as I only want to show one column with checkboxes and "Select/Clear All" links. Everything is working as expected. Now, I wanted to add a scrollbar to my grid control, I did add the scroll bar using div but what it does is, it includes the "Select All and Clear All" links aswell. I only need to add the scrollbar to datarows and not to the header.I am trying to extend my control to include hte scrollbar by adding div during Render function. But how will I determine or loop through header rows? How will i get the header row with hyperlinks that I created above?? In Render if I do this.HeaderRow, it gets the original column header and not the custom header.
View 1 RepliesI've build a custom server control inheriting from WebControl. Basically it is a kind of button. All is working perfectly except one thing: the PostBackUrl is inoperative.
I probably forgot to implement something. Actually I just added the property PostBackUrl. Probably I should also implement an interface of call something.
