Forms Data Controls :: Referencing Contents Of Gridview Cell?
Jan 9, 2010
I' working on an Office Supplies website for a college course I'm doing. I have most of the website created, I'm just working on the shopping cart element of it now.
When the user goes to check out, I have a Gridview displaying the items the user wishes to buy as follows, it contains 3 columns, REF NBR, Product Name and Quantity, when the user clicks on the 'BUY NOW' button I want to take all the reference numbers from the Gridview and search teh database and deduct the Quantity from the number of items in stock.
I know I'll have to have a loop to read through the gridview, but how do I reference the contains of the Gridview REF NBR cell ?
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)
I'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
While handling the Edit link button I need to use the value in the BoundField, UserName. Unfortunately during the OnRowEditing handler, all strings are empty "". This is also true in the ensuing OnRowDataBound handler for the row in question where e.Row.RowState == DataControlRowState.Edit. Is there a way to obtain this value after the user clicks on the Edit link, and commences the OnRowEditing event?
I've got a gridview (gvwDepartment) which has within it a template column containing another gridview(gvwEmployees) and a formview(fvwProfile). I want to be able to select the profile of each employee(in fvwProfile) whenever I click on the select button to select him in gvwEmployees. How do I go about that?
I have an imagebutton control in the column HeaderTemplate of a gridview and want to know how to reference the imagebutton so I can add an attribute to it programmatically. Following is the code for my gridview control:
[Code]....
I can reference the checkbox control correctly with CheckBox chkbox = GridView1.FindControl("chkSelected") as CheckBox;However, I have tried the following code for the imagebutton but I get the error message Object reference not set to an instance of an object.:
[Code]....
Or is the OnInit event handler the right place to reference the control?

I have a gridView which connect with sqlDatasource. I want get value from cell. When i do that - this.GridMain.Rows[1].Cells[9].Text but always there are "". How can a i get value form cells.
With a Gridview, if I have a boundfield or templatefiled with visible="false" I can't get the data. I need access to some data of a field, but don't want to have it showing up in the gridview.How do I do that?
I have a gridview that is populated from a selection made from a dropdown list box.
I would like to add a button that will select the returned results being displayed in the gridview so that the data can be copied to the clipboard for use in another app like excel.
The size of the gridview will vary depending on the selections made in the drop down.
How to set Height and ItemSource(Business Object as DataSource for Cell) for every Cell in DataGrid/ Grid? Shown below is part of code I am currently using with Grid Control. What I am currently doing is that I am using ListBoxItem, set Item Height and ItemSource at ListBoxItem Level, Add ListBoxitem to ListBox and then Add ListBox to Grid, It leaves me with just one row and multiple columns in the Grid, which is perhaps not the best way of doing it as it doesn't allow me to take benefits from UI Virtualization of Grid.
[code]....
I am open to use any control i.e. Grid/ DataGrid provided it allows me to set Cell Height and item source at Cell level. In my requirement, Cell height depends on the Item duration and size of image, which means the height of the cells may not be same across cells in any particular row.
I have a 2008 c# application that displays data in a gridview. Two of the columns can contain text up to 500 characters. I have been able to handle these in the gridview by displaying the long text in a scrolling div tag. That works fine in the gridview, but when I export the gridview to excel, the row-height autofits to the large text fields, giving extremely tall rows. Any idea on how I can control the formatting to limit the row-height for the output excel spreadsheet? The approach I use for the export is described in
I am using this command to get the value of a particular cell in the GridView: Question: Do you know why I do not get a value in strValue ? There is definitely value in the grid.
protected void grid_RowCommand(object sender, GridViewCommandEventArgs e) { //proceed only if the Details button is clicked... if (e.CommandName.ToLower() == "details") { //Get the row index selected... int index = Convert.ToInt32(e.CommandArgument); GridViewRow row = grid.Rows[index]; string strValue = grid.Rows[index].Cells[1].Text; }
i am having trouble to set a new value to a specific GridView cell.
The value is passed from a javascript to the c# code behind where it should update a specific Gridview cell []:
I am not using editedtemplate.
code c# :
[code]....
In other hand I am using a JS code that set a GridView cell value.. The new value is set but as soon as i select another row on the GridView ..the Updated cell comes back to its original.
JS code1 :
setCellValue(selectedIndex,5);
JS code2 :
[code]....
What i need is a simple way to set a specific gridview cell with my passed JS variable.
It does not give me any errors and seems to work but the grid view cell do not take this session. When I'm clicking on the edit hyperlink this event is triggered.
Objective : Get the value of a particular cell in a particular row - when I click on a template field button link. How do I "select" that row so I can use code like datagridview.rowselected
or datagridview.selectedrowindex etc...
Right now I am using code like that and it does not get any values of the gridview because it does not know what the selected row is (may be because I want this to be done on template field click)
I have a gridview with a bound column,a template field with an editable textbox and a template field with a readonly textbox.
The bound field value is coming from database. I will enter a value to the editable textbox field. I want to set a value to the third cell based on the entered value in second cell . If the second cell is lost focus i want to set the value to third cell . If the solution is with a javascript function i will be very happy.
