Gridview OnRowDataBound Loop Through Cells?
Jan 7, 2011I'm using ASP.net 4. How do I loop and read the value of each cell in a row with the OnRowDataBound event?

View 1 RepliesI have a form that contains a asp:Table and it contains 2 rows with 6 columns.
Also on my form is a gridview. It contains one row with 6 columns. (see pic)
I'd like to see if I can format both so that they appear to have the same over-all width and cell width too.
I'd like to know if it's possible to do this in the source view - rather than programmatically.
In the pic, the top is the grid view and underneath is the table.
What's the best method for looping through a table, grabbing all the data in the cells, but skipping the <th>? Do I put the data in an array?
View 1 RepliesI have a calendar control that has a checkbox control added to each cell on dayrender. A user will check the dates that they want to add an event for and click a button that will display the modaldialog box where the user will enter the event for the selected dates. I'm having trouble looping through the calendar dates to get the checkbox contol's checked property.
View 2 RepliesI can't get control which I added in DataGrid. I am adding it in OnRowDataBound event like:
protected void RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowState == DataControlRowState.Edit || e.Row.RowState == (DataControlRowState.Alternate | DataControlRowState.Edit))
//int cindex = 0;
//for (cindex = 0; cindex < e.Row.Controls.Count; cindex++)
foreach (Control ctl in e.Row.Controls)
{
DataControlFieldCell dcctl = (DataControlFieldCell)ctl;
TableCell tcell = (TableCell)dcctl;
Label lblComment = new Label();
TextBox txtComment = new TextBox();
lblComment.Text = "<br>Comment: ";
dcctl.Controls.Add(lblComment);
dcctl.Controls.Add(txtComment);
//tcell.Controls.Add(lblComment);
//tcell.Controls.Add(txtComment);
//e.Row.Cells[cindex].Controls.Add(lblComment);
//e.Row.Cells[cindex].Controls.Add(txtComment);
What is happening here: there is already exist one TextBox in TableCell by default and I want to add another one TextBox and Label. After the bounding I can see 2 textboxes, I can input data into the both, but when I click Update button, then raises OnRowUpdating event where I can't get my TextBox!
protected void RowUpdating(object sender, GridViewUpdateEventArgs e)
{
grdView.EditIndex = -1;
int counter = 0;
for (counter = 0; counter < grdView.Rows[e.RowIndex].Cells.Count; counter++)
{
foreach (Control ctl in grdView.Rows[e.RowIndex].Cells[counter].Controls)
{
And here I will be getting only default one TextBox (with its value). But my TextBox is disappeared! :(
P.S. I can't use predifined columns, like asp:TemplateField in aspx file, because my table has different amount of rows every time. It is dynamic
What is GridView Event "RowDataBound" ?
When it is used ? And How ?
how to bind dropdownlist in gridview in row databound event in asp.net?
View 1 RepliesIn a GridView control ASP.NET
OnRowDataBound="gvTest_OnRowDataBound" followed by
protected void gvTest_OnRowDataBound(....){}
OR
Text='<%# BindMyData(DataBinder.Eval(Container,"DataItem.Price"), DataBinder.Eval(Container,"DataItem.CurrencyID")) %>'
followed by
protected string BindMyData(object price, object currencyID)
{...}
Which one is best in terms of performance and coding best practice?
All of my columns are bound in the Gridview. On OnRowDataBound event, I am adding some custom styles like underlines and colors to the text of the columns. Sorting of data is working fine but I am losing my custom styles when I sort. I am using the generic sorting code for the GridView.
How I can keep my custom styles on sorting that I added during OnRowDataBound event.
I'm using a standard GridView control inside of a web form. The web form uses a master page. The application is running within sharepoint (wss 3.0) environment. When i attach both the OnRowCommand and OnRowDatabound events to the gridview as shown in the markup below, only the OnRowDataBound event fires. The OnRowCommand never gets hit. When i press a button on a row, it posts back but never hits the onRowCommand event and simply falls through and repaints the page . However if i remove the OnRowDataBound event, the OnRowCommand event starts to fires correctly. I've tried a number of things...1. Hooking up the events in code instead of markup. (inside of PageLoad or PageInit)2. Changing the order in which the events are attached.

I want to save data to a different table. My save is working fine but the challenge is that it saves empty cells as well.I will like to save only QTyDelivered cell with value. Any empty QTyDelivered cell should be ignored (which means the row of QTyDelivered cell that is empty will not be saved) .How can i achieve this?

How to do it using VB.NET ?
I'm relatively new to ASP, so this may be a simple fix that I am just not figuring out (here's hoping!). I am working in VisualStudio2010 using C#.
Basically, I have a table in SQL with the following columns: Product, ProductGroup, Attribute1Value, Attribute2Value, Attribute3Value
For each ProductGroup, the Attribute definition is different. For instance, in ProductGroup1, Attribute1 is Size and Attribute1Value might be 2,3,5, etc. In ProductGroup2, Attribute1 is Quality and the Attribute1Values would be Standard, Economy, Premium, etc.
I will only ever pull in one Product Group at a time and would like to have my column headers reflect the Attribute definition (Header= Size rather than Attribute1Value when applicable".
What I would like to do is pull in a gridview that is invisible with the columns ProductGroup, Attribute1, Attribute2, Attribute3 and then assign the values within the column to be variables that I can use to reassign my column headers. I have been able to set column headers based on other variables (specifically the selected value from a dropdown), but am having trouble with the code to set variables equal to gridview values.
When I tried
protected void Page_Load(object sender, EventArgs e)
{
lblAttribute1.Text = GridView4.Rows[0].Cells[2].Text;
}
protected void RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
e.Row.Cells[3].Text = lblAttribute1.Text;
}
}
I got the error message that my index was out of range. I thought at first that this may be because my Gridviews have no rows upon page load, only after a few selections from DropDowns, but I don't know if they are at all related. Is there a better way to do this in general?

View 1 RepliesOn my desktop the application when showing the gridview does not wrap cells. Now when I publish the application to the (internal) web server it wraps some of the cells. I have set the wrap attribute = false but does not seem to work. Running IE8.
Code:
<RowStyle Wrap="False" Font-Size="10px" />
<AlternatingRowStyle BackColor="#FFFFC0" Wrap="False" Font-Size="10px" />

for that how can i merge the date in datagridview make it into single column.
Note it is windows application.
CellPadding only applies the padding to the header row. CssClass in Gridview, RowStyle or EditRowStyle has no effect.

I'm using a GridView to display some columns and rows that reside in a database. This works excellent. Because i wanted to add columns dynamically out of a List of names. Let's say we have a list with 5 names in it, then it dynamically creates a column for every name in the GridView.
Here's some code to display what i do:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
//Create columns for each student
List<Student> allStudents = new Eetlijst.Business.Students().GetAll();
allStudents.Reverse();.......
How do i create the dynamic columns for each row? I create them with a DataBound event. So when the GridView databinds, the columns get filled with data. There is also a check inside to see if the row is in edit mode or not. So when i click on the edit button next to the row, the row goes perfectly in edit mode. The code i made adds a TextBox control to the cell.
When i fill in a value and press the Update button, it can't find any controls anymore and therefore i can't get the value i entered. The control is still there in the DataBound when i put a break point after it. But as soon as i click the Update button, all the controls of the cells are gone.
I searched on the internet and all i found is that it has something to do with the application firing a postback before it reaches the RowUpdating method.
So, how can i let the controls exist that i added to the cell when it is in edit mode?
