MultiView GridView DataKeyNames Link To Many View SQLDataSources?
Jun 7, 2010
I have a MultiView control with 3 View controls inside it.
View1 contains a GridView control with 2 DataKeyNames assigned.
View2 contains a FormView and a DetailsView control.
View3 contains several DetailsView controls.
When a row is selected in the Gridview I'd like to update View2 to show data relating to the selected row DataKeyName 1 and View3 to show data relating to the selected row DataKeyNames 1 and 2.
I have previously tried configuring the SQLDataSource to use a WHERE clause setting the Source Control to the GridView object but I couldn't get it to work. There was nowhere to state which DataKeyName to use as the parameter.
i'm getting error on finding control from grid's row.control is an imagebutton which is placed inside a template field.my requirement is if add to cart button is clicked and if that particular book has its volums then it should show message that you need to see its detail and then after selecting its volume you can add it to cart...but i'm trapped in where i'hv to attach bookcod with querystring which is in datakey names of grid. The datagrid has one column only and thats template field..
I have a grid view with a few columns, for example a column in the grid view contains description of a product. The description might be very long, so i want to display only first 100 characters of the description and then provide a . when we click on the. then the whole description should be displayed.
using vb.net/asp.net 2005 I have a multiview with views inside and I want to show the first view (view0) on pageLoad but dont know how to do this. also how do I change the view when the user clicks a button?
If you use the multiview and view controls you'll notice that there's about 1/4 of an inch of unusable space at the top of the view.Is there any way I can eliminate that space?
I have three views inside a Multiview How to activate one by one view means I Just want to change the Active View Index of the Multiview using javascript in ClientSide How can i do this?
How to set the bgcolor of an asp.net cell from code behind using a value from a sqldatasource?
I have a working sql data source that is used to populate labels in my html form using asp.net.
The background color of the cell depends on a comparison of the actual value versus the target value. If the actual daily value exceeds the limit I would like to change the bgcolor of a cell in the web page. The actual value comes from one datasource and the limit comes from a 2nd data source.
In vb code behind I would like to accomplish the following pseudo code:
If (sqlsource1Total > sqlsource2Limit) Then bgXCell.BgColor = "#ccff99" Else bgXCell.BgColor = "#ff9999" End If
I have to set GridView.DataKeyNames(This is really a question about the syntax for a string array, in VB.Net.)
I am discovering the PrimaryKey columns names from within a loop, ie:
For Each fld As IEntityField In Me.llbDataSource.EntityCollection(0).PrimaryKeyFields 'fld.Name ' this is where the column name is stored, so I have to get this into an array Next I can not use this syntax.
So, basically, how does one declare a string array (as required by GridView.DataKeyNames), and then populate the elements of the array from within a loop?
I have a generic List which is populated with an object which has properties like FirstName, Surname etc.
If I bind a gridview to the list with autocompletecolumns = true, the Gridview displays the data in the List.
The code looks like:
[code]....
My question is:
How do I populate the DataKeyNames with the properties (FirstName, Surname) contained in the object that is contained in each element of the Generic List?
From what I understand within the Gridview Object you can have many datakeynames.
I have the field like this DataKeyNames = "id1, id2"
However, i don't know how to access the DataKeyNames individualy. For example. How do you access the first ID for the for a given row or the 2nd ID for a given row????
Since I am using 2 DataKeyName is Gridview, so I have to pass both the DataKey while deleting Row from Gridview(using "Image Button" of Gridview).I tried it using below lines:
string name = GridView1.DataKeys[gvrow.RowIndex].Value["G_Name"].ToString(); string id = GridView1.DataKeys[gvrow.RowIndex].Value["Param_ID"].ToString();
I need a way to change the ActiveViewIndex of a multiview control based on some query results. Right now I test to see if I have rows returned from my linq query. If so, set a certain view active. If no rows are returned, I would like to set a different view active. I would like to do this on Page_Load if possible.
Right now I get the fatal "Object reference not set to an instance of an object" error on page load with it bombing at line 12. My count is given a value at runtime so that is not the issue. Can anybody tell me why this is and how to get around it. Code is attached.
I also tried this both the pre render and Page_Init event but both yielded the same behavior with the Object reference not set to an instance of an object error. I can do this just fine in an onclick event for a button, but now I need a way to run a test and set the default view when the page loads. Seecode below
protected void Page_Load(object sender, EventArgs e) { eCrystalPSGDBDataContext psgDB = new eCrystalPSGDBDataContext(); int count = (from st in psgDB.studyTbls where st.patientid_i == Convert.ToInt32(Request.QueryString["PatientId"]) && st.studystatusid_i == 1 select st).Count();if (count == 0)else if (count == 0) { StudyInfoMultiView.ActiveViewIndex = 1; } else { StudyInfoMultiView.ActiveViewIndex = 2; } }
I have 2 pages page1 and page2, page1 has a button and page2 has a multiview with many viewswhat I need is:when I click on the button in page1 I want to go to a specific view in page2 ex: view3
I have a MultiView inside an updatePanelThis MultiView has 7 Viewin each view I have Two button (next, prev) I have two fileupload in view6 and two button (btn_nextSix and btn_prevFive)I put this code in updatepanel
And found after click on btn_nextSix, fup_pic.hasfile is true but by clicking in last button (btn_reg) I found fup_pic.hasfile is false so I changed my code like this (I putted all buttons in multiview in triggers)...
I have a Datalist Which is Bind with Database..Datalist Displays Image And their Image Name.. Now i Want Details of Selected Image from Database in Next View (View 2).
Also Want to know which control should i use for click event on Image??ImageButton or <a Href="">?My Code is --
I have two columns in my Gridview marked false for the visible property but which are clearly listed in the DataKeyNames that are still getting set to null in my database table on update.
The first one is a column MId# which is a type int. It starts as 0 but on edit is turned into null. The Second is RequireSKU which is also converted to null.
I am did Gridview delete and rebind data using json and jquery like this
<script type="text/javascript"> $(document).ready(function () { $(".deleteGridRecord").click(function () { //Get the Id of the record to delete var record_id = $(this).attr("id");
[Code] ....
But i want to set DataKeyNames properties of grid view in above code dynamically how can do this....
