Data Controls :: Validation For Dynamic Gridview Cells
Dec 8, 2013
In my gridview i have
I have a dropdownlist with tables. if i select the table, based on the columns the gridview displays.
One table contains 9 columns and other contains 40 columns... for example....see the below.
Insert/Edit RoleUID RoleID Role Desc ....etc columns
Here RoleId, role are mandatory fields... i am making those two with "*" red color. but if i click on the "INSERT" then i need to get a alert msg that the roleid is mandatory.. you should enter in interger value, and if "role" is null then same like "Role is mandatory... plz enter character value"
I don't have any template fields in the gridview. i make autogeneratecolumns=true in my grid.
I need validation for the dynamic gridview cell... where there is no columns fixed...
I generate dynamic grids based on a count value returned from some DB tables. the code for it goes like this : I give and Id to each grid that is generated.
if (myDataList1.Count >= 1) { for (int i = 0; i < myDataList1.Count; i++) { //retrieving the exact i count from pageload ViewState.Add("newCount", i); //creating the dynamic grid with its corresponding gridview properties. grvDynamic = new GridView(); grvDynamic.ID = "GridView" + (i+3); grvDynamic.AutoGenerateColumns = false; grvDynamic.RowCreated += GridViewRowCreated; grvDynamic.RowDataBound += grvDynamic_RowDataBound; //adding bound field columns to retrieve data from stored proc BoundField metric = new BoundField(); metric.HeaderText = "Goal "; metric.DataField = "metric"; grvDynamic.Columns.Add(metric); BoundField mtd = new BoundField(); mtd.HeaderText = "MTD"; mtd.DataField = "value_MTD"; grvDynamic.Columns.Add(mtd); BoundField goal = new BoundField(); goal.HeaderText = "Tier Level Achieved"; goal.DataField = "value_goal"; goal.HeaderStyle.Width = Unit.Percentage(10); grvDynamic.Columns.Add(goal); BoundField you1 = new BoundField(); you1.HeaderText = "Month End"; you1.DataField = "firstLevel_you"; grvDynamic.Columns.Add(you1); BoundField you2 = new BoundField(); you2.HeaderText = "Month End"; you2.DataField = "secondLevel_you"; grvDynamic.Columns.Add(you2); ButtonField singleClick = new ButtonField(); singleClick.CommandName = "clickHyperlink"; singleClick.Visible = false; grvDynamic.Columns.Add(singleClick); BoundField metricId = new BoundField(); metricId.HeaderText = "Metric Id"; metricId.DataField = "metricID"; metricId.Visible = true; grvDynamic.Columns.Add(metricId); //binding the gridview to data. grvDynamic.DataSource = data; grvDynamic.DataBind(); grvDynamic.Columns[5].Visible = false; } }
protected void grvDynamic_RowDataBound(object sender, GridViewRowEventArgs e) { //this basically gets the metric Id's of rows with the ishyperlink flag set to 'Y'. I need to make these particular cells clickable var isClickable = (from md in myDataList3 where md.IsHyperLinkFlag == 'Y' &&
md.value_MTD != null select md.metricID).ToList(); if (e.Row.RowType == DataControlRowType.DataRow) { // Get reference to button field in the gridview. LinkButton _singleClickButton = (LinkButton)e.Row.Cells[5].Controls[0];
This code works perfectly fine , depending on the ishyperlink flag in the database...specific cells in the grid are made clickable and then redirected to page2.aspx My Issue: I need to capture which specific cell in which specific grid the user has clicked. store some information in sessions based on the cell clicked and use that information in page2.aspx.
2)drop down list to select the control to be added.
3)button is an ADD button .
when the "ADD" button is clicked the text entered in the "caption" text box has to appear in the first cell of the first row in the table and the control selected from the dropdown list has to be added to the second cell of the same row. similarly many such captions and controls have to be dynamically addded to the successive rows of the table as per user selection ( note: the previously selected control and caption label must persist on furthur selections .
how do i go about the adding controls and the text into the table part ?
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?

I'm working on a project in vb.net framework 2.0 and have a column that has server names. I have the accessdb sql setup to order by the db, what I would like to do is to have it look like the following picture below. I'm pretty stumped on how to do it as the methods I've found online haven't worked so well. Also just a small tid-bit the gridview is bound to a ddl which selects the application and the gridview refreshes with server data. Country would be server name and state would be the environment.

specially VB code behind pages.I am writing an app with a colleague and I am stuck on something.he app is a holiday booking calendar.

we're creating a GridView to display news articles programmatically (not using a SQL database).
We can create & display the GridView, but are having a devil of the time to get the hyperlinks in SetupGrid() attached to the titles
of the articles in the GridView. Below is our .aspx code and .vb code of how we create the GridView. Any ideas on what we should do to get the hyperlinks array of strHyperlinks() in SetupGrid() to be applied to the titles in column 1 of the GridView?
I have a gridview that has both a select and an update statement. One of the cells is a date cell, and the other is for numerics only. Is there a way I can do this? At the moment, anything can be keyed into the cells and this results in an error as my update stored procedure expects a date value and a numeric value respectively.
While uploading excelsheet to datatable and bind it to gridview it will check blank data in excel sheet and when it will bind to gridview,the row in which blank present that row will be in red background color and the other row will occur in normal back color.
