Forms Data Controls :: Get GridView Cell By Column Name Using Row Reference
Jul 19, 2010
I have an ASP.NET/C# web application that has a GridView control. In the last column of that GridView control I have a template field that contains a menu. In the OnMenuItemClick event I get a reference to which row the event was fired from, in order to determine what value the ID field contains for the current row. Currently I reference this cell by it's index "gvr.Cells[1].Text". However, this is highly volatile since any changes to the location of the ID column breaks the code. How can I instead gain the value in the cell that has a column name (or some other name-like property) of "SomeID" from a GridViewRow reference?
However the the column in the gridview is dynamic created which might more or less depend on system logic.
I have try to set the column width in row_created event, rowDataBound event, but it show me that no column is available by using gridview.columns.count.
I have a ASP.NET/C# web application that contains user controls with GridView controls. The GridView controls contain the following column types.
CommandField - Contains buttons like Edit, Select, Delete, ... BoundField (x8) - Contains the data fields from the database. TemplateField - Contains a single ASP:Menu control.
The menu control consists of the following structure.
Navigate To (Parent MenuItem) - Location A (Child MenuItems) - Location B - Location C - Location D - Location E
What I need to do is when the OnMenuItemClick event is fired, determine which menu item was clicked (already done) and then capture what the value in the first BoundField cell is for the row that the menu item was clicked on.
So, for instance if I have three rows in the grid with the first BoundField column containing the IDs 1, 2 & 3. Then I hover my mouse over the menu on the 2nd row, and click the menu item "Location C". The "Menu1_OnMenuItemClick" event is fired and I can determine that "Location C" was clicked by e.Item.Value == "Location C".
However, how do I navigate up through the API to determine what the contents of the cell in the first bound field column are for the row that was clicked on?
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
I developed the grid view in which i define 2 columns(Common Name, Common ID). I wanted that when i edit particular cell of grid; if i select any cell of column "Common Name" then it tells the name of particular column name and when i click on any cell of column "Column ID", it shows that column name.
I have a GridView, in which the width of each column is dynamic and changes depending on the dataset. I need to get the width of each column for use in my PDF exporter, but the column/cells width is always '0', presumably because I haven't set the width property.
I want to display gridview column heading when mouse over to the particular column in the gridview.I am working in VisualStudio 2005 with MS.Net2.0 framework.I don't want to use ajax.
I have a gridview which is binded to a Sqldatasource. I would like to replace a column data field value to 'Not Applicable' if that column has got a value of 2 in database.
i need to do a pop up for every cell in gridview. The moment user click on the cell on gridview , a pop up pop up and showing every the data in the cell for user to do modification in textbox.
I am facing the problem in capturing the cell data and also bind the pop up to every cell.
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.
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 am using GridView ,I want to do a validation like if i edit any one of the Cell in that column, it will through the validation when the sum of column value is more than 100. How can i do this validation?
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.
