Forms Data Controls :: Dynamic Tooltip For Gridview Cell
Feb 24, 2010
My GridView rows have a field for a server timestamp when a person entered in a particular state(like idle). I want to show the time elapsed since the person has been in that particular state. That I want to show as a tooltip when mouse is hovered over the cell and time elapsed calculation I want to do on client side only without a roundtrip to the server. In RowDataBound event of the GridView I add functions to the show and hide the tooltip by following some examples on the web. In the JavaScipt function, I calculate the time elapsed. But it works first time but not after that somehow and I get a JScript error "Microsoft JScript runtime error: Function expected." on this line:
My GridView is inside a user control which is used as a ASP.NET web part and my web part zones are inside ASP.NET UpdatePanel. Could it cause a problem?
I have a listview with 5 columns and i will bind the data from database for all these 5 columns. It may have "n" number of rows. But some items may not have values so for the empty cell i need to display some tooltip. How to do this?
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.
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 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 have two command buttons in my gridview that I need to set tooltips for. Both buttons show as an image and I need to fix it so it show a message like 'Click here to edit'. The gridview control is databound and I have the all of the functionality of it working, I just need to be able to do this.
Iam doing a Page in which the i have a lables in the template field of gridview so on the onmouseover on label i need to show the tooltip with dynamic data along with image
i am trying to implement this vb codes to my gridview for showing fixed char and with tooltip.My NewsHeader column property in sql is Text. How can I correct this error?
If there's a better way to accomplish what I'm attempting I haven't found it yet. That being said, I have create a gridview like the one here,[URL]And with some minor tweaking it working great for all my fields, checkboxes, etc. The issue is my last column is another gridview, and I'd like it to function the same. that is, a dynamic gridview inside of a dynamic gridview. I get that I have to create it initially with null values or it won't show up. I guess what I'm having trouble figuring out is instead of go will null data in the parent gridviews column, do I place my blank child gridview. Do I create and bind the child gridview first, or second. Generally just not sure. Also, as far as storing the data from the child gridview goes, will each one need it's own datatable?
I have a griview which is bounded to a sqldatasource and changed dynamically. How do I change the background cell color based on the value? e.g., 0-0.5 green, 0.5-1 red, sth like that.
Alright, so I have a Gridview which is bound to a stored procedure. The stored procedure uses cross tab functionality to count customer data / types, and then display it like this ...
Code:

Now this is where I'm stumped ... each data cell (or cell that displays the count of data for that column / row), need to be a link, and upon clicking that link, a pop up or something will bring up another gridview or list listing all those clients or customers. For example, if you click on row 2, cell 2 (519), then it will open a gridview or list of all 519 of those clients. This basically means each cell will have to represent a different query, unless I use dynamic sql somehow... Does anyone have any idea how I might be able to accomplish this.
Inside Gridview's particular column's every Row I want to open a pop up "on-mouse over", in which i can show different Image of area (diferent image for different row)
Also, i want same requirement "on-mouse over" of Label.
My GridView is:
Stations State Danger Value

For every Stations row, I want to display different area image "onmouse over" .. How to achieve?
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 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; }
